Improvements to Checks focused around Keystone Process count

+ Check for Keystone Process count on Controllers
+ Removed thread count check as it would inadvertently prevent correct
  checking of Keystone Process count
+ .gitignore files that should not be introduced into repo
+ Add .yml extension to checks group_vars
