* Update packages/grafana-toolkit/README.md

Allow extending LDFALGS by setting LDFLAGS to be able to pass
-zrelro,-znow for Arch Linux packaging
to get full relro.

If grafana is build from a non-git source a new timestamp is used every build which makes grafana binaries
non-reproducible.

Motivation: https://reproducible-builds.org

Adds the definition of `GetTeamsForLDAPGroupCommand` which handles the lookup of team information based on LDAP groupDNs.

This is an Enterprise only feature. To diferentiate,a response will contain the `team` key as `null` on OSS while on Enterprise the key will contain an empty array `[]` when no teams are found.

Fixes #18941

* Moved loop

Fixes #18902

* LDAP: Add API endpoint to query the LDAP server(s) status|

This endpoint returns the current status(es) of the configured LDAP server(s).

The status of each server is verified by dialling and if no error is returned we assume the server is operational.

This is the last piece I'll produce as an API before moving into #18759 and see the view come to life.

This change adds formal support for the South African Rand in the list of currencies.

* ErrorHandling: Error boundary for every container

* Remvoe custom query editor errors
