Revert "Revert "Merge branch 'haus-add_pe_facts_to_stdlib' into 2.4.x""

This reverts commit d6d23b495cda0e154b4e73982acc43e586564c0e.

This backwards-compatible additional functionality is targeted at the
next minor release.  There are already backwards-incompatible changes in
the master branch so we need to establish a new minor branch.

+# Fact: is_pe, pe_version, pe_major_version, pe_minor_version, pe_patch_version

+# Purpose: Return various facts about the PE state of the system
+#
+# Resolution: Uses a regex match against puppetversion to determine whether the
+#   machine has Puppet Enterprise installed, and what version (overall, major,
+#   minor, patch) is installed.

+# Caveats:
