This is just a small add-on to Hunter's commits where he added
extra parameters to support PE. This commit just cleans up
some of my old comments that were made irrelevant or inaccurate
due to the work that he did, and adds a bit of documentation to
the new test manifest that he created.
This commit does the following:
* Use the new inifile module to manage puppet.conf
* More comprehensive management of config files
* Validate database connectivity before applying puppetdb
config changes
* Validate puppetdb connectivity before applying puppet
master config changes
* Documentation
