* LDAP: use only one struct

* Use only models.ExternalUserInfo

* Add additional helper method :/

* Move all the helpers to one module

* LDAP: refactoring

* Rename some of the public methods and change their behaviour

* Remove outdated methods

* Simplify logic

* More tests
  There is no and never were tests for settings.go, added tests for helper
  methods (cover is now about 100% for them). Added tests for the main
  LDAP logic, but there is some stuff to add. Dial() is not tested and not
  decoupled. It might be a challenge to do it properly

* Restructure tests:
   * they wouldn't depend on external modules
   * more consistent naming
   * logical division

* More guards for erroneous paths

* Login: make login service an explicit dependency

* LDAP: remove no longer needed test helper fns

* LDAP: remove useless import

* LDAP: Use new interface in multildap module

* LDAP: corrections for the groups of multiple users

* In case there is several users their groups weren't detected correctly

* Simplify helpers module

* ensure that empty Elasticsearch queries are properly set to *.  Fixes issue that appears when passing raw data from variables.

* combine null check and empty check into one

* Implementation of optimistic lock pattern

Try to insert the remote cache key and handle integrity error

* Remove transaction

Integrity error inside a transaction results in deadlock

* Remove check for existing remote cache key

Is no longer needed since integrity constrain violations are handled

* Add check for integrity constrain violation

Do not update the row if the insert statement fails
for other than an integrity constrain violation

* Handle failing inserts because of deadlocks

If the insert statement fails because of a deadlock
try to update the row

* Add utility function for returning SQL error code

Useful for debugging

* Add logging for failing expired cache key deletion

Do not shallow it completely

* Revert "Add utility function for returning SQL error code"

This reverts commit 8e0b82c79633e7d8bc350823cbbab2ac7a58c0a5.

* Better log for failing deletion of expired cache key

* Add some comments

* Remove check for existing cache key

Attempt to insert the key without checking if it's already there
and handle the error situations

* Do not propagate deadlocks created during update

Most probably somebody else is trying to insert/update
the key at the same time so it is safe enough to ignore it

Explore: Includes context parameter when invoking getExploreState() from Prometheus datasource (#17569)

Closes #17457

* Tests: Updates truth screen shot

* Fix: Fixes an implicit any error

This fix prevents Grafana from crashing after being logged in.

these are currently defaulted to false (off) until the next minor release.

fixes #17392

Same idea as with the `gosec`, `revive` and etc.
Allows you to execute `make bra` as pinned local dependency instead
as global one. And therefore alleviates dependency installation issues.

README also updated - I was thinking to provide verbose installation instructions
for it. Since with that way we assume make is installed on the
developer system.

But it might be premature right now?
