Cirrus: Add RHEL-7 testing

Add necessary tweaks to base-image build/import process so that image
can successfully boot with networking enabled.  Build the base image and
update ``.cirrus.yml`` accordingly.

Also make a minor improvement to cache-image building to help save space in
GCP image storage.  Namely, instead of storing every produced image, export
them into google storage buckets w/ life-cycle enabled.  For production use,
they may be converted back into GCE images, otherwise they will expire after
a time.
