Update ldap docs

Related to gitlab-org/gitlab-ee#397

@axil What do you think of moving LDAP configuration docs to `adminstration/auth/ldap.md`? Then we'll probably need to add the relevant group link configuration piece to some user group documentation. We can cross-link and deprecate the current `integration/ldap.md` location.

Fuzzy search dropdown UI element min-width (issue 14644)
