* Prometheus: Add off switch for metric/label name lookup
This will help users with amounts of metric name
data that is too much for a browser to handle.
Autocomplete will be disabled and metrics chooser hidden,
since obviously both rely on this data.
Fixes#22702
* Use onUpdateDatasourceJsonDataOptionChecked
... from `@grafana/data`. Refactor naming to faciliate its
use and stick with prop names as passed down from
`ConfigEditor`.
PLUS:
- Rephrase switch label, add a tooltip and reduce the
size of the to what "Custom query parameters" originally
was.
- Change `languageProvider` type in `PromQueryField`.
* Put language provider back in
Functions and history still work, even when metrics
lookup gets disabled.
Also: Rewording of setting.
* Display a message when lookup got disabled manually
* Call property for setting disableMetricsLookup
* Show disabled metrics chooser instead of warning
... in `componentDidUpdate`, not just `componentDidMount`.
Also unify query field behavior of Explore with Dashboard - when the
data source changes, it doesn't unmount but instead refreshes its
metrics.

* Prometheus: Display HELP and TYPE of metrics if available
- Prometheus recently added a metadata API around HELP and TYPE of
metrics
- request metadata when datasource instance is created
- use metadata to show help and type in typeahead suggestions and in
metrics selector as tooltip
* Fix types
- 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
