Add live-iso output support to lorax-composer

This ended up requiring more intrusive changes, but it should be the
most complex of the output types. After moving the core of
livemedia-creator into a function I added more settings to compose_args,
and more defaults to start_build. It now pulls the release information
from /etc/os-release, and produces a bootable .iso
