The arching goal of this commit is to enable single user
synchronisation with LDAP. Also, it included minor fixes of style,
error messages and minor bug fixing.

The changes are:

- bug: The `multildap` package has its own errors when the user is
  not found. We fixed the conditional branch on this error by asserting
on the `multildap` errors as opposed to the `ldap` one

- bug: The previous interface usage of `RevokeAllUserTokens` did not
  work as expected. This replaces the manual injection of the service by
leveraging the service injected as part of the `server` struct.

- chore: Better error messages around not finding the user in LDAP.

- fix: Enable the single sync button and disable it when we receive an
  error from LDAP. Please note, that you can enable it by dispatching
the error. This allows you to try again without having to reload the
page.

- fix: Move the sync info to the top, then move the sync button above
  that information and clearfix to have more harmony with the UI.

* Fix: Adds Explore menuitem to React Panels
Fixes #19865

* Refactor: Adds CMD|CTRL+click to Explore menu item

* Elasticsearch: Support rendering in logs panel

- add "Logs" metric query type so panels can inform the datasource that
the query is a logs query
- datasource modifies target when metric query type `logs` is detected
- then existing log result processeing paths are followed

* Fix failing test, number of agg types changed

* Notifications: Add alert_state to the kafka message Fixes #11401

* Renamed ttl config in code to be more consistent with behaviour
* Introduced new setting `sync_ttl` in .ini file
* Keeping the old setting `ldap_sync_ttl` in the .ini file as fallback and compatibility.

Provisioning of dashboards now always overwrite existing ones and does not look at the configuration `allowUiUpdates` anymore

* Adding grafana plugin version info

It was unclear if one can specify the plugin version to the environment variable. It is possible and works fine. Added it to the plugin information.

* Update typo docs/sources/installation/docker.md

* Applied all comments

Moved the information to make it more readable, fixed typos and added missing punctuation.

* Rewording and better example

More feedback, added example text. Did not manage to get newline for the example.

* added the missing space

* query mixed

* query mixed

* batch queries

assumption is that msi MAX_PATH is effectively 130 (260/2) for the full path of the filename (Dir + filename), and this causes error LGHT0103 : The system cannot find the file in the msi build.
