auth: Make supported authentication backends a bitfield on realm.

Browse Source 
This makes it possible to configure only certain authentication
methods to be enabled on a per-realm basis.

Note that the authentication_methods_dict function (which checks what
backends are supported on the realm) requires an in function import
due to a circular dependency.
