Includes a collection of utility and subplans that can be assembled to
add a new external database componenet to a PEADM deployment, a required
component of the Extra Large architecture. Databases can be added in
both DR and no-DR deployments or if a database is lost, replaced using
a still functioning replica as a source of data.

Was originally operating under the assumption that availability group
A's database would look to B for reads, eventually realized this was
incorrect so removed the functionality.

Adding some comments and renaming the plan responsible for installation
so that it is generic, as opposed to database specific.

Changes logic which decides when and where to start, stop, or restart
Puppet Server and PuppetDB so that orchestration over PCP is always
available.

Cleans up some code along the way.

External database component installation

The "A" group is configured to use the "B" compiler lb; the logic didn't
reflect this, and assumed the configured compiler on the "A" group was
the "A" compiler - which doesn't make sense.

This commit fixes the incidental swap.

Rename the action to "Release Prep" (better matches what it does) and
also provide an optional input value which can be used to supply a
GitHub personal access token, in order to avoid throttled API request
to GitHub when using github-changelog-generator.

Haven't figured out a way to securely provide this access automatically,
but it's not too arduous to require it of the action runner.
