TPA-RFC-77-H: Move Tails nodes to the TPA Puppet Server

Full plan: TPA-RFC-77

Move Tails nodes to the TPA Puppet server:

• Install all 3rd-party modules that are used by Tails but not by Tor
• Import the tails::profile::puppet::eyaml profile into TPA's profile::puppet::server
• Copy the EYAML keys from the Tails to the Tor puppet server, and adapt hiera.yaml to use them
• Copy code (legacy modules and profiles) from Tails to Tor
• Include the corresponding base class (profile::tails or profile::common) depending on whether the node's role starts with tails_ or not.
• Point Tails nodes to the Tor Puppet server
