MXS-1167: Skip loading of users for internal services at startup

Browse Source 
When MaxScale is being started and the users are loaded, the MySQL
authenticator should not load the database users for internal services
abstracted as servers.

The loading of users at startup for internal services is avoided because
the startup is done in a single thread context and the internal services
have not yet been started.

The delayed loading of users will cause the authentication to fail when
the first client connect. This triggers the reloading of the users and the
second attempt at authentication will succeed. All of this is hidden from
the end user.
