Created a url_for function module to be used by different javascript
modules to use the same functionality of flask at client side.
A python module can expose the list of endpoints, used by its
javascripts, by overriding the 'get_exposed_url_endpoints(self)'
function.
In this patch, we have modified all the browser modules to use this
function. It will allow us to move the majority of the javascript
modules of browser nodes from templates directory to the static
directory.
TODO::
- Move these javascripts modules to the static directory.
- Use this function in all the applicable javascript modules.
e.g. tools, miscellaneous modules
- The CSS class 'slick-row' has been renamed to 'sr'
- The CSS class 'slick-cell' has been renamed to 'sc'
- The SQL Editor included an unused 'normal_row' class on each row which has been removed as it was unreferenced in the code or CSS.
The intent of these changes is to minimise memory usage by the grid, by saving a few bytes per row/cell.
It's questionable how much difference this actually makes given that SlickGrid updates the document so it
only includes the visible rows on the fly, but every little helps.
1. When an existing schedule updated, or a new schedule is added from a pgAgent job dialog, it was not able to generate the proper update SQL Query.
2. The SubNodeCollectionControl was not removing the grid, when it is being getting removed.
- Added DatetimepickerControl, MomentCell (using moment.js)
- Used the 'DatetimepickerControl' in Role (Also - resolved an issue, when unset the datetime for 'Valid Until'.)
- Added a 'Select All/Unselect All' adaptor for Select2 used by pgAgent nodes.
- Fixed an issue with SubNodeCollectionControl, which was not starting the modification session of the child model, when created default value for collection is not null/undefined. And, hence - validation on the child model was not working.
- Fixed a memory leak with SqlFieldControl, and SqlTabControl, which was not releasing the CodeMirror properly.

This patch takes care of:
* Consistent behaviour during create, update operation on any node.
- It should return the node data during creating a new object, or
updating the existing one.
* Now that - we have consistent behaviour during these operations, we
can consistently move, update the tree item based the node data from
the server.
* Implemented the methods for each node to get the information about
that particular node only.
* Using the above changes to implement the 'refresh' operation on tree
node properly.
I must thank Surinder, and Harshal for helping me implement the 'node'
method, and also changed the behaviour of create & update methods to
return the node data for most of the nodes.
Fixes#1244
Made backend changes for:
* Taking care of the connection status in the psycopg2 driver. And, when
the connection is lost, it throws a exception with 503 http status
message, and connection lost information in it.
* Allowing the flask application to propagate the exceptions even in the
release mode.
* Utilising the existing password (while reconnection, if not
disconnected explicitly).
* Introduced a new ajax response message 'service_unavailable' (http
status code: 503), which suggests temporary service unavailable.
Client (front-end) changes:
* To handle the connection lost of a database server for different
operations by generating proper events, and handle them properly.
Removed the connection status check code from different nodes, so that
- it generates the proper exception, when accessing the non-alive
connection.

1. Select2 control fixed for multi-select mode.
2. Index constrains (primary and unique key) fixed column listing issue.

and we need to parse the values again in float at client side.
different resize event callbacks for a particular dialog.
This function needs to be executed from the 'build' function of any of

file control selection button.
All our views are inherited from the Backform.Form (a extended
Backbone.View), which has an tag element set to 'form'. The default
action for a button in form is to submit the data, and that results into
undesirable redirection within our Views. We can resolve the issue of
redirection by setting 'preventDefault' to true in the click event
object on that button. But - we may use the button control within our
view in future, and that will have the similar behaviour. Keeping that
in mind, we set the default tag to 'div' instead of 'form' for all our
views.

- Rename file/folder not working in list view.
- Selection folder only should not allow to select file.
- Ui changes in table list to match with the pgadmin color styles.
- Custom STORAGE_DIR path don't list files/folders when opened in window

We will be using the external utilities like pg_dump, pg_dumpall,
pg_restore in background. pgAdmin 4 can be run as a CGI script, hence -
it is not good idea to run those utility in a controlled environment.
The process executor will run them in background, and we will execute
the process executor in detached mode.
Now that - the process executor runs in detached mode, we need an
observer, which will look at the status of the processes. It also reads
output, and error logs on demand.

- SQL code folding was not supported in codemirror so added the same.
will always have latest data related to that type of node. Also, fixed
the cache_level for different node types.
This commit also contains fixes for the following issue:
* In extension module - use the 'node-list-by-name' instead of using a
custom 'node-ajax-options' control, and removed redundant template
schemas from it.
* When we tries to destroy the select2 object from
Select2Cell/Select2Control while releasing the properties view,
sometimes select2 can not find the instance related it for some
unknown reason. Hence - before removing it we will check for manual
instance existance using $.data('select2').
* When we traverse through the browser tree nodes very quickly, it tries
to remove the object before it gets created completely, and results
into an exception.
* Icon in the select2 drop down list was not visible due to some CSS
issues.
Apart of that, we will generate two new browser events -
'pgadmin-node:created:<NODE-TYPE>', 'pgadmin-node:updated:<NODE-TYPE>'
whenever a new node is created, or an existing node will be updated.
Also, remove the CodeMirror object for better clean up process.
When a SQL control/tab is rendered in a hidden element, it does not
render really well. Because - it rely on the height, and width of the
container to count the gutten position, and margin, and other elements.
Hence - whenever the tab, panel becomes visible, we will refresh the
control.
Select2 does not allow to scroll any of the parent container once it was
opened, and if it was not properly closed.
Also, resolved an issue - existing selection was not working, while
re-rendering the Select2Cell.
Removed the use of separate editor for both of these cell types. There
were two instance of select2 were getting created in the Select2Cell,
one in the Select2Cell itself, and another in Select2CellEditor. And,
loosing the focus mysteriously, and making the scrollbar in the property
dialog non-responsive.
Also, modified the NodeAjaxOptionsCell to use the above logic, and
removed its own version of render function to make it consitent across
the system.
This patch [changes sent by Murtuza] also includes improvisation in the
DeleteCell, and ObjectCell, which will honour now 'canRemoveRow', and
''canEditRow' respective properties of Column.
The current implementaton binds the cell/control object, and the ajax
data in the asychronous Cells/Controls with the 'options' functions
extended from the Select2Cell.
The problem starts when we try to fetch the current model from that
options/transform/filter function to do some operation, which does not
require in most of the cases. Except the privileges control - where we
needed the current model for omitting the existing selected object
during transformation, and filtering.
In order resolved the issue, we need a common object, which is shared
among the Cell. In backgrid, the 'Column' object is mong the cell,
hence - implementation logic has been changed to bid the 'Column' object
with the 'options' function and, passed the 'Cell' object as an
arguments.
Because - we do use the common function 'transform' between 'Control'
and 'Cell', we needed make changes in the Select2Control to pass the
Control object as an arguments.
And, make the changes in the privileges control to use the new
implementation. The same logic is also required in some of the
operations, we will be/are working on the table/column nodes.
This allows us to use the Backgrid key navigation as expected.
This has also resulted into an issue - related unresponsive scrollbar
issue in the SubNodeControl.

order to fix the issue rendering the context menu for longer text.
Needs to do some modification in the existing pgAdmin4 CSS theme to make

Following are the enhancements:
1. Added border to control which was missing earlier.
2. Allows user to provide height to sql-field control by specifying extraClasses field in model schema.
3. Defined new classes for sql-field control height in overrides.css
4. Added scrollbar to the control.
Usage:
{
id: 'definition', label:'{{ _("Definition") }}', cell: 'string',
type: 'text', mode: ['create', 'edit'], group: 'Definition',
control: Backform.SqlFieldControl, extraClasses:['custom_height_css_class']
}
change events.
- In input & textarea control, call the change event on key up (but -
not on every key up events, wait for sometime before trigger that
event, so that - we do not overdo that).
- In unique/subnode control, whenever we create new model object, set
all the required static fields used by pgAdmin form generation logic.
- In NodeAjaxListCell, we don't need to call the list generation
operation (ajax operation) for each and every cell. They use the same
shared column object.

This patch also includes an issue related to IntegerControl, which does
not emit any error message, when it has some issues.
In order to fix the issue, it will trigger 'pgadmin-session:invalid'
event, when the input value is not an valid integer.
It will be used by the nodes like view, which require to show the code
inside as one parameter.
Also, override the events for the Backform.TextareaControl in order
handle some cases, which were not handling the change in textarea
properly in all situations.
Also, we need to show the error message around the input control with
name attribute only.
