Add configuration for Cirrus-CI

Testing podman requires exercising on a full-blown VM.  The current
containerized-approach is complicated, and mostly a band-aid over
shortcomings in the other CI systems.  Namely, we want:

* To pre-build environments with dependencies to reduce the
  setup time needed for testing.
* The ability to verify the pre-built environments are working
  before utilizing them for further testing.
* A simple, single set of flexible automation instructions to
  reduce maintenance burden.
* Ease of environment reproduction across clouds or locally, for
  debugging failures.

This change leverages Cirrus-CI + Packer + collection of shell scripts
to realize all of the above.
