Some tweaks to first_available_file mostly in terms of error handling and not trying src= to be present
as it is not used here.

make it useful from /usr/bin/ansible and the API.  Also some minor style fixes.

first_if_available and yum fixes

Added `list=status` to include the output of `service <cmd> status`.
