This commit adds mappings for Puppet Enterprise 2023.3 to puppet8.

(PA-5337) PE integration

(PA-5287) Remove MAC OS 10.15 support

stdlib 9 dropped the is_function_available() function. I reworked the
code to check if `pe_anchor` is defined. The code now works with Puppet
core functions and is compatible with Puppet 7/8, probably 6, and does
not rely on stdlib.

(PA-5309) Add macOS 13 (ARM) to the puppet_agent module task

This commit updates config_setting.pp and adds any missing puppet 7.x and 8.x
settings. Some puppet 8.x specific settings, like `ca_refresh_interval` are
being added. The agent will ignore any settings it does not understand/support.

Implement stdlib 9 compatibility

(PA-5691) Add missing puppet settings to config_setting.pp

This code was last updated in Oct 2020 and all this time we've been testing
"upgrades" from 7.x to 5.5.21. This only recently started to fail when stdlib v9
was released as the root_home fact uses Ruby syntax that's not valid in Puppet
5/Ruby 2.1.9.

It's not practical to update the upgrade tests after each release. And we already test
upgrades and idempotency in the acceptance/tests/*, so delete these tests.

This changes the class_spec to initally manage puppet; puppet 7 and
puppet 8 both are not enabled or running after installation, so
there could be a bug in the initscripts somewhere or this was never
actually a feature but a bug in how the tests were run.

(maint) Delete duplicate test

Windows requires the current puppet collection to be specified in
the puppet_agent class, so that is refactored to be globally
specified in the `spec_helper_acceptance`. Additionally, logic and
mocking was added to specifiy default install paths for the VERSION
file for both linux and windows.

…indows

(maint) Make spec tests pass on windows

AIX 7.1 is not supported in puppet8 and will be removed from puppet7 in the near
future.

(PA-5721) Add puppet8 and drop puppet5 support from AIX

This commit updates and applies the 2.7.5 PDK template to prepare for
the v1.15.0 release and make using the GitHub Changelog Generator easier.

When updating the module to PDK 2.7.5, the Vox Beaker gem was removed.
puppetlabs_spec_helper updated and the updated version removed the Beaker rake
task which is used for acceptance testing.

This commit adds the voxpupuli-acceptance gem which re-adds the Beaker rake task.

This commit includes all the changes needed to pass the validate rake/check
which checks if the module adheres to the Puppet Strings style.

This commit blocks the top_scope_facts, only_variable_string, and
strinct_indent lint check for portions of manifests/install/windows.pp,
manifests/osfamily/redhat.pp, and manifests/osfamily/suse.pp respectively.

For the top_scope_facts, the check keeps on thinking
`puppet_agent::_expected_package_version` in windows.pp is a fact. For the
only_variable_string, when I try to remove the double quotes from
`"${facts['os']['release']['major']}"`, the conditional no longer works as
expected in redhat.pp. Lastly, for the strict_indent check, it thinks the
indentation for $script in redhat.pp and suse.pp is wrong but it is not.

Currentlty, the puppet_url_without_modules assumes all puppet:/// URLs are
using the modules mount. pe_packages is a custom mount and does not use the
modules mount.

(maint) PDK Update 2.7.5

Currently, the "Static Code Analysis / Run checks" will fail on release prep
PRs because the check does not include "Release prep". This commit updates the
commits Rake task to check for "Release prep" in the PR title/name.

(maint) Update commits.rake to check for "Release prep"

Release prep v4.15.0
