Manage additional groups for users allowed to authenticate.

This endpoint allows you to create, read, update, and delete configuration
for LDAP groups that are allowed to authenticate, and associate policies to
them.
Deleting a group will not revoke auth for prior authenticated users in that
group. To do this, do a revoke on "login/<username>" for
the usernames you want revoked.
