Modify `LDAP::Person` to return username value based on attributes

`Gitlab::LDAP::Person` did not respect the LDAP attributes username
configuration and would simply return the uid value. There are
cases where users would like to specify a different username field
to allow more friendly GitLab usernames. For example, it's common
in AD to have sAMAccountName be an employee ID like `A12345` while
the local part of the email address is more human-friendly.
