Fix playbooks after change to running all plugins in a single binary / single process

[chungers]

Recent changes (e.g. PR #702) to consolidate multiple plugin binaries / containers / processes into a single binary / process require updates to the playbooks:

• Simplify the startup of the plugins
• The naming of sockets / plugin names have been simplified and the new names (kinds) need to be reflected in the playbooks (e.g. those for provisioning single instance or groups calling the plugins).
