* incapsulates multipleldap logic under one module
* abstracts users upsert and get logic
* changes some of the text error messages and import sort sequence
* heavily refactors the LDAP module – LDAP module now only deals with LDAP related behaviour
* integrates affected auth_proxy module and their tests
* refactoring of the auth_proxy logic
* Feature: add cron setting for the ldap settings
* Move ldap configuration read to special function
* Introduce cron setting (no docs for it yet, pending approval)
* Chore: duplicate ldap module as a service
* Feature: implement active sync
This is very early preliminary implementation of active sync.
There is only one thing that's going right for this code - it works.
Aside from that, there is no tests, error handling, docs, transactions,
it's very much duplicative and etc.
But this is the overall direction with architecture I'm going for
* Chore: introduce login service
* Chore: gradually switch to ldap service
* Chore: use new approach for auth_proxy
* Chore: use new approach along with refactoring
* Chore: use new ldap interface for auth_proxy
* Chore: improve auth_proxy and subsequently ldap
* Chore: more of the refactoring bits
* Chore: address comments from code review
* Chore: more refactoring stuff
* Chore: make linter happy
* Chore: add cron dep for grafana enterprise
* Chore: initialize config package var
* Chore: disable gosec for now
* Chore: update dependencies
* Chore: remove unused module
* Chore: address review comments
* Chore: make linter happy
