Feature migrate to multiple ldaps

Still needs some documentation.

Basic flow:
- Upgrade to the newest EE
- Change gitlab.yml to include the server hash
- Run `rake gitlab:migrate_ldap_providers`

This will ensure all current ldap groups links will continue working.

See merge request !200

Add a few items to changelog

See merge request !1187

Issue respect single sign on

Fixes #1677 by making sure the per-build user is saved as well. Otherwise the user is passed to devise, and the user is saved afterwards, creating a successful signup.

See merge request !1186

Because devise will trigger a save, allowing unsaved users to login, behaviour had changed.
The current implementation returns a pre-build user, which can be saved without errors.

Reported in #1677
