Prior to this commit, the -I argument was not passed with the `pidstat`
command, which resulted in inaccurate results. This commit adds the `-I`
argument to `pidstat` to divide the `%usr` and `%cpu` by the number of
processors.

* add idempotency acceptance testing

* add fixtures required for testing

* fixed spec helper

This commit removes the files and class declaration for collecting
ActiveMQ metrics.  It leaves the parameters in the main class definition
to avoid breaking upgrades if set.

This commit adds some PuppetDB message queuing metrics to the default
collection. The additional metrics add data about the command processing
and queueing within PuppetDB.

This commit replaces cron entries with systemd services and timers.  It
also fixes the existing tests and adds a few to the pe_metric spec tests:

* When systemd is not the init provider
* Collecting and not collecting Puppet server metrics
* Customizing the collection interval

SUP-2192 Migration from Cron, to SystemD timers for Database Maintenance

Add PuppetDB message queue metrics

…_cpus

(GH-95) Use -I with pidstat with system_processes

Prior to this commit, we instantiated the pe_metric defined types with
"puppet_" in their title.  This created issues in the scripts related to
validating the names of the services and output directories.  This
commit changes the defined type to include the "puppet_" prefix.

Rework namevar of defined types

Add pe_metric acceptance test and improve init spec test

This commit adds some acceptance tests to validate the service status on
the timers, updates some naming conventions, and checks for metrics
collection.

(maint) Add acceptance tests for the services

PE Version and PDK Update

This commit adds the --stream option to the bolt provision master
commands. This will aid in visibility into the plan execution while
looking at the acceptance tests.

This commit removes Puppet 5.x support within the module. Puppet 5.x is
EOL and will no longer be tested in this module.

This commit removes support for operating systems that do not use
SystemD. SystemD is a requirement of this module moving forward as the
cron jobs have been replaced with SystemD timers.

(SUP-2493) Remove Puppet 5.x support

(SUP-2493) Remove support for SysVinit operating systems

This commit removes OracleLinux-8 and Scientific-8 from the
metadata.json. These operating systems are not in facterdb and cannot be
tested.

(maint) Remove Oracle 8 and Scientific 8

(maint) Add the stream option to bolt

Prior to this commit, the default was to manage the sysstat package by
default. This commit changes the default to not manage the sysstat
package. It includes logic to only include the system metrics collection
classes when the sysstat package is installed and adds a notify when the
packge is not installed.

(GH-108) Disable sysstat management by default

Prior to this commit, there was no way to ship the system level metrics
to a remote metrics server. This commit adds that capability to keep it
inline with the pe_metrics capabilities.

Prior to this commit, there was no way to ship vmware metrics to a
remote metrics server. This commit adds the capability of doing metrics
shipping for VMware metrics.

Prior to this commit, there was no way to ship postgres metrics to a
remote metrics server. This commit adds the capability of doing metrics
shipping for postgres metrics.

Prior to this commit, there was logic in pe_metric to determine the
metric shipping information for the command in cron. This commit moves
that logic out to the existing function.

Prior to this commit, the ace and bolt pe_metrics were not passing a
parameter into the pe_metric type but did have it in their parameters.
This commit passes that parameter into the pe_metric type.

This commit fixes some spec and rubocop errors due to a rebase with the
main branch.
