Allow datasource connection to postgres with password "scram-sha-256" 
authentification.

Fixes #14662

Fixes #17665

This commit addresses half of #13749 by making sure GetMetricData 
works for alerting. Math Expressions (compound metrics) will still not 
work for alerting, this would require a bigger refactoring of Grafana's 
alerting service. However, with this commit at least alerting for basic 
metrics with non empty query Id will work.

Fixes half of #13749

* CI: Added metric to track strict null errros

* Update scripts/ci-frontend-metrics.sh

* Auth: Do not search for the user twice

Previously `initContextWithBasicAuth` did not use `LoginUserQuery`, doing
`GetUserByLoginQuery` only i.e. looking user in DB only, things changed when
this function started to check LDAP provider via `LoginUserQuery` (#6940),
however, this request was placed after `GetUserByLoginQuery`, so we first
looking in DB then in the LDAP - if LDAP user hasn't logged in we will
not find it in DB, so `LoginUserQuery` will never be reached.

`LoginUserQuery` request already performs `GetUserByLoginQuery`
request in correct sequence. So we can just remove redundant request.

* Correct sequence execution during authentification &
  introduce tests for it

* Move basic auth tests to separate test file, since main test file already
  pretty large

* Introduce `testing.go` for the middleware module

* Remove redundant test helper function

* Make handler names more explicit

Closes #18037

Create and push the expected tag to grafana-dev repository
and use this instead for running the end to end tests
for the release.

The `oauth_state` cookie used to be created with the SameSite value set
according to the `cookie_samesite` configuration.
However, due to a Safari bug SameSite=None or SameSite=invalid are treated
as Strict which results in "missing saved state" OAuth login failures
because the cookie is not sent with the redirect requests to the OAuth
provider.
This commit always creates the `oauth_state` cookie with SameSite=Lax
to compensate for this.

* Add types and rewrite datasourceChanged to async/await
