Disable the zaqar-messaging service user

The zaqar::keystone::auth_websocket class has been added to create
an independent keystone endpoint for websocket service but the service
user created by the class has never been used.
This change disables the logic to create the user and the associated
resources like roles and projects, so that only required resources are
created.
