Adds support for collecting metrics from backend plugins and
exposing them thru Grafana's Prometheus metrics endpoint.
Enables to check health of backend plugin by using the route
`/api/plugins/<plugin id>/health`.
Uses sdk v0.6.0.
Closes#20984
Backend plugins is recommended to use hclog with json
formatting to get proper log output in grafana server log.
Old hclog-wrapper.go that I deleted while back is still in
the repo so deletes that.

- new builtin datasource plugin "Logging" (likely going to be renamed)
- plugin implements no panel ctrls yet, only ships datasource
- new models for logging data as first class citizen (aside from table
and time_series model)
- Logs as new view for Explore
- JSON view for development
Testable only against existing logish deployment.
Then test with queries like `{job="..."} regexp`.
Adds a datasource selector to the Explore UI. Only datasource plugins
that have `explore: true` in their `plugin.json` can be selected.
- adds datasource selector (based on react-select) to explore UI
- adds getExploreSources to datasource service
- new `explore` flag in datasource plugins model
- Prometheus plugin enabled explore
