The implemented toggling UX is similar to how the dashboard graph plugin
behaves. Also incorporates review feedback to persist series visibility
state by means of the alias property, with the limitation it carries
too.

- added dedup switches to logs view
- strategy 'exact' matches rows that are exact (except for dates)
- strategy 'numbers' strips all numbers
- strategy 'signature' strips all letters and numbers to that only whitespace and punctuation remains
- added duplication indicator next to log level
- replace the Graph/Table buttons with toggle control in a wrapper panel
- moved toggle control to left to be close to the label
- removed panel styles from Logs and Graph viewer
- moved loader animation to panel
Explore is about keeping context between datasources if possible. When
changing from metrics to logging, some of the filtering can be kept to
narrow down logging streams relevant to the metrics.
- adds `importQueries` function in language providers
- query import dependent on origin datasource
- implemented prometheus-to-logging import: keeping label selectors
that are common to both datasources
- added types
Datasource selection triggers a connection test, on success
the DS is set in the Explore state. If the test takes long and user
selects a different DS, and just after that the first test succeeds,
then the first DS overwrites the state.
* when test returns check if datasource is still the requested one
- Logging gets a graph for log distribution (currently per stream, but I
think I'll change that to per log-level)
- added grid columns for timestamp and unique labels
- show common labels of streams
- View options to show/hide time columns, label columns
- created `--small` modifier for Switch CSS classes
- merging of streams is now a datasource responsibility
this is a fix-up PR that cleans up Explore Logging after the recent
restructuring.
- log results need to be merged since query transactions have been
introduced
- logging DS has its own language provider, query field, and start page
(some of them based on prometheus components)
- added loader animation to log viewer
- removed logging logic from prometheus components
- when instantiating a datasource, the datasource service checks if the
plugin module exports Explore components, and if so, attaches them to
the datasource
- Explore component makes all major internal pluggable from a datasource
`exploreComponents` property
- Moved Prometheus query field to promehteus datasource and registered
it as an exported Explore component
- Added new Start page for Explore, also exported from the datasource
Implements rudimentary support for placeholder values inside a string
with the `PlaceholdersBuffer` class. The latter helps the newly added
sum aggregation query suggestion to automatically focus on the label
so users can easily choose from the available typeahead options.

- use global range types
- add ErrorBoundary around individual Explore components
- fix table merge on empty results
- fix TimePicker date parsing on ISO dates
- fix TimePicker range string after relative move
Existing querying was grouped together before handed over to the
datasource. This slowed down result display to however long the slowest
query took.
- create one query transaction per result viewer (graph, table, etc.)
and query row
- track latencies for each transaction
- show results as soon as they are being received
- loading indicator on graph and query button to indicate that queries
are still running and that results are incomplete
- properly discard transactions when removing or changing queries
In short, the underlying problem appears to be the `onChange()` handler
being triggered after handling the blur event. Since the contents have
not actually changed this forces the typeahead state to reset which
undesirably puts a stop to propagating the selected suggestion back up
to get set.

- Extracted table panel's merge logic to combine multiple tables into one
- Put the merge logic into the table model as it merges multiple table
models
- make use of merge in Explore's table query response handler
- copied tests over to table model spec, kept essential tests in
transformer spec
These changes were originally intended to address a bug whereby a
suggestion for an already selected label value continues to appear.
However, they also appear to fix several other problems in the area:
- Wrong suggestions when using negated label matching operators
- Misaligned label value suggestion replacements

- adds react-table as dependency
- replaces custom table component in Explore
- vendors react-table styles and overrides them (currently in
explore.scss)
- use react-highlight-words
- add highlighting (color and border) to the matching substring of the
suggested items in the typeahead
- extracted match finding from logging datasource
- created new utils/text.ts class for text-related functions
- added more types
- some syntax rules are loaded asynchronously
- when they have been received, the query field needs to re-render
- trigger re-render via bogus edit (tried other methods but could not
find any)
- remove `edited` property of query objects
- query object semantics changes to be initial values only
- resetting or externally modifying a query is done via giving it a new
react key, which replaces the row completely
- query changes while typing are sent up to Explore to be saved in a
local property that is not part of the component state (prevent
control circle)
- all Explore functions using the queries must access the local property
for current values
Storing queries, split state, and time range in URL.
- harmonize query serialization when generating Explore URLs in
dashboards (use of `renderUrl`)
- move URL parse/serialization to Wrapper
- keep UI states under two keys, one for left and one for right Explore
- add option to angular router to not reload page on search change
- add lots of types
- fix time service function that gets triggered by URL change
