project_domain_id set instead of project_domain_domain-name in server.pp

[Erik McCormick]

In server.pp we set project_domain_id with a value of 'Default' if not specified.

  $project_domain_id = 'Default',

Since we no longer have a domain with an id of 'Default', but rather create one that gets a UUID, this will break if not explicitly set to the UUID. In other modules, we set project_domain_name instead, and should do that here as well.

I just realized this is also the case for user_domain_id. This should also be user_domain_name.

The usage of *_domain_id was already removed, so I'll close this now.
