Fix capitalization & typos in the InfluxDB data source docs.

In the data sources docs two similar subsection names were used.
This PR renames `Adding the data source to Grafana` subsection to
`Adding data source` so that all data sources have the same
subsection name.

Adding all currently available panels to the basic_concepts.md

* Explore: Remove datasource testing on selector

- datasource testing gets in the way of fast query iteration: switching
between datasources can take seconds
- it should not be explore's duty to test datasources in the first place
- removed the concept of datasourceError in Explore, should not be its
concern
- datasource erorrs will express themselves in query errors just fine
- connection errors are still bubbled up
- removed reconnection logic from explore, should not be its concern
- missing labels in loki are still "visible" via an empty label selector
- Loki and Prometheus treated connection errors differently than other
datasources, making sure to pass through the original error message

* Show datasource error in query field for prom/loki/influx

* Removed connection test case, fixed disabled state

* Enable `errcheck` for golangci-lint
* Fix linting errors
* pkg/plugins: Fix tests
