Cirrus: Implement podman automation 2.0

Reimplement CI-automation to remove accumulated technical-debt and
optimize workflow.  The task-dependency graph designed goal was to
shorten it's depth and increase width (i.e. more parallelism).  A
reduction in redundant building (and 3rd party module download) was
also realized by caching `$GOPATH` and `$GOCACHE` early on.  This
cache is then reused in favor of a fresh clone of the repository
(when possible).

Note: The system tests typically execute MUCH faster than the
integration tests.  However, contrary to a fail-fast/fail-early
principal, they are executed last.  This was implemented due to
debug-ability related concerns/preferences of the primary
(golang-centric) project developers.
