Convert all authenticator implementations to receive their
configuration from auth::config instead of accessing db::config
through the query processor:
- password_authenticator: reads superuser name and salted password
from config, stores them as members
- saslauthd_authenticator: reads socket path from config
- certificate_authenticator: reads role queries from config
- transitional_authenticator: passes config to inner
password_authenticator
- maintenance_socket_authenticator: inherits new constructor
via using declaration

This patch removes class registrator usage in auth module.
It is not used after switching to factory functor initialization
of auth service.
Several role manager, authenticator, and authorizer name variables
are returned as well, and hardcoded inside qualified_java_name method,
since that is the only place they are ever used.

In a follow-up patch in this patch series class registrator will be removed.
Adding transitional.hh file will be necessary to expose the authenticator and authorizer.
