Add support for users database on disk. (#262)

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`.
