Previously, several magic strings were in place to affect cirrus-ci
operations. Two were buried within scripts. One to optionally
execute system-tests within a PR. Another to avoid re-building
cache-images upon every merge.
Move these magic strings out into the open, buy locating their
logic up-front in the ``.cirrus.yml`` file. This improves
readability and reduces surprise/astonishment at runtime.

Given frequent merges, it doesn't make sense to rebuild the VM testing
images every time. Instead, monitor the PR title and description for
a magic string, only triggering builds on a match:
***CIRRUS: REBUILD IMAGES***

An invalid GCE value is being passed to packer, preventing it from
building VM images. Fix this, and centralize the definition of the
image name suffix by setting it at ``setup_environment.sh`` call-time,
rather encoding inside packer's `libpod_images.json`. This makes
the value available for use by other scripts.
Also, switch the unique component of the name, to be based on the
commit-sha being tested. This will improve traceability, since the git
history is more permanent than the `CIRRUS_BUILD_ID` env. var. The
later is subject to log-rotation, destroying evidence of the images
source state.

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.
