Make ansible speak to appropriate puppetmaster

With split puppet master infrastructure ansible needs to be told which
puppetmaster to talk to. Do this by making puppetmaster a required
argument to the puppet ansible playbook.

Since we can't rely on the cert listing while this is happening also add
puppet master specific host list files which can be used to specify
which hosts talk to which puppetmaster via the new ansible playbook
feature.
