Since React and other dependencies bump caused some troubles with building packages that @kaydelaney and me tried to debug without any success, we decided to revert React 16.9.0 bump.

* Update the way context is retrieved for Loki
Major changes:
1. getLogRowContext expects row to be of LogRowModel type
2. getLogRowContext accepts generic options object, specific to a datasource of interest. limit option has been removed, and now it's a part of Loki's context query options (see below)
3. LogRowContextProvider performs two queries now. Before, it was Loki ds that performed queries in both directions when getLogRowContext.
4. Loki's getLogRowContext accepts options object of a type:
interface LokiContextQueryOptions {
direction?: 'BACKWARD' | 'FORWARD';
limit?: number;
}
This will enable querying in either direction independently and also slightly simplifies the way query errors are handled.
LogRowContextProvider maps the results to a Loki specific context types, basically string[][], as raw log lines are displayed in first version.

* (feat/explore): Support for new LogQL filtering syntax
Loki is adding syntax to support chained filtering.
This PR adapts Grafana to support this.
- Send only `query` parameter in loki request
- Automatically wrap search text in simple syntax, e.g., `{} foo` is
sent as `{} |~ "foo"`.
* Adapted to regexp parameter staying on in Loki
* Dont wrap single regexp in new filter syntax
* Fix datasource test
* Fallback regexp parameter for legacy queries
* Fix search highlighting
* Make highlighting work for filter chains
* Fix datasource test
* fix(explore): Prevent double querying for Prometheus and Loki
- queries were triggered twice because two Enter handlers existed
- removed runner plugin from Loki and Prom query fields (runner plugin
is still being used in azure)
Part of #16995
* Set loki's mtrics capability to false
Loki is not a metrics store. Explore was using the `metrics` field in
the plugin definition to issue a second query run. But Loki shows only
one result viewer.

This is the first step moving towards Explore supporting logs for
more datasources than Loki. In the first step we move all the log
processing from Loki into Explore.
- Make explore convert logs result returned from datasources to SeriesData,
if needed, and for now convert SeriesData to LogsModel.
- Loki datasource query now returns SeriesData and all
processing have been moved into explore instead.
- Removed key from LogRowModel and use log row indexes as
the unique key instead.
- Removed id from LogsModel since it looks like it's not in use.
- Introduced a new class FieldCache which is convenient to use when
looking up multiple fields and/or field types and series values.
