init: Adding lshw -xml in log file

When logging the local setup configuration, it could be very useful
embedding the "lshw -xml" into it to provide much more information to
remotely understand if the detect.py did a bad detection or if the
hardware is really missing or mis-configured.
ansible: More Red Hat dependencies that doen't come as standard (at least with RHEL7) but
are needed to build the various base images
common: Only attempt to mount the ISO image if it isn't already mounted
This allows for one .install script to call another withouth triggering
  mount: <iso> is already mounted
