Extract some of the ACI Tree functionalities, and decouple it from the
main source. Also - create some abstractions from the repeated code
around the enable/disable the schema children object create/edit/delete
functionalities, and also created the dialog wrappers for backup and
restore dialogs.

This is the first version of our Tree implementation. At this point is a
very simple tree without no abstractions and with code that eventually
is not very performant, but this is only the first iteration and we are
trying to follow the 'Last Responsible Moment Principle' [1].
Implemention details:
- Creation of PGBrowser.treeMenu
- Initial version of the Tree Adaptor 'pgadmin/static/js/tree/tree.js'
- TreeFake test double that can replace the Tree for testing purposes
- Tests, As an interesting asside because Fake’s need to behave like
the real object you will noticed that there are tests for this type
of double and they the same as of the real object.
