The possible values for ACL policies are now: bypass, one_factor, two_factor,
deny.
This change also deprecate auth_methods because the method is now associated
directly to a resource in the ACLs instead of a domain.
In order to simplify the deployment of Authelia for
testing, LDAP is now optional made optional thanks
to users database stored in a file. One can update
the file manually even while Authelia is running.
With this feature the minimal configuration requires
only two components: Authelia and nginx.
The users database is obviously made for development
environments only as it prevents Authelia to be scaled
to more than one instance.
Note: Configuration has been updated. Key `ldap` has
been nested in `authentication_backend`.
