We allow users to configure LDAP attribute preferences. For example,
email can be configured to use `mail`, `email` and `userPrincipalName`,
falling through to the next until a value is found. Prior to this
change, Gitlab::LDAP::Person did not honor this configuration. Now,
the class will honor `name` and `mail` configuration. It does not
handle `username`, or fallback to `first_name` + `last_name` in the
absence of `name`.

Also added relevant specs and refactored to_references in a bunch of places to be more consistent.

Test cases were not waiting for page load after clicking.
This caused failures in test cases that were executed right after
these incorrect ones, because of requests hitting server after
a test was finished.
We do not have to click links, we can go directly to a correct page
by passing parameters in the URL.

This allows the test to pass when your local time zone is different
than UTC.
"Date Format" JavaScript library uses a custom, non-standard format
when displaying time zone part of the datetime. There is no point in
trying to replicate this behavior in Ruby.

* Simplify code around group parent access check

Closes #26145

This spec would hang due to the use of transactions, and would
incorrectly stub Thread.new.
