Adding postfix plugin for ohai-solo
Adde few minor modifications...
Fixed a little bit, responsible for showing INFO message when postfix is not installed from RPM/DEB packages
Added changes suggested by Caleb, including removal of some redundant code to make it faster, and use things discovered by other plugins
Adding modifications suggested by Caleb
Removed dependancy on platform_family, and fixed a small typo, that revented the final part (config discovery) from working. However I left the IF statement as it is a catch for custom installs (non package installs)
Redesigned it slightly, to accomadate latest suggestions from Caleb (getting rid of postconf being executed twice etc..)
Adding few suggestions from Nico, regarding finding the postfix process, as well as removing one methong call, I forgot to remove last time. In find process method I did some changes, so it returns a PID and the process executable
Added changes suggested by Ryan, as well as discovering a little bug (when postfix is installed but not running, the plugin would not handle that and would crash, due to the find_process() method thrying to do a split on an empty string... ). Now when postfix is installed and not running, the plugin returns: Master Process: Postfix is not running!
Use split over chomp and clean up spacing
Disable ipv6 on CentOS because yum repos are flakey
