correction for ordering and state management in testing

Prior to this commit the exclusion list was named
`exclude_self_service_indicators`. This commit updates the parameter
name to `indicator_exclusions` and does some minor formatting changes.

Prior to this commit, the facts did not have full paths to the `puppet`
executable. This commit updates to use the full paths and simplifies the
logic where it was simple.

(maint) Minor linting

Prior to this commit, the logic for checking the service state depended
on running the `puppet resource` face from an exec. This commit adds
some code to use `Puppet::Type` and provides methods to check the
service states in a shared module.

(maint) Move service logic to a module

Adds additional indicators

Adds in PE node confinement types and more status checks

Prior to this commit, S0007 used existing facts to check the free disk
space. This commit adds a shared method to check the disk space of an
arbitrary filesytem path and uses it for S0007 and S0008.

Prior to this commit, the acceptance test was checking that all elements
in the fact hash were not false, however it did not specify the number
of elements in the hash This could lead to a scenario where a chunk is
missing and still passes. This commit checks the explicit number of
chunks in the hash.

Adds a filesystem free method

Prior to this commit, the class would fail with an error if the
self_service fact was not present. This commit updates the code to
handle a missing self_service fact.
