new system tests under BATS

Initial attempt at writing a framework for podman system tests.
The idea is to define a useful set of primitives that will
make it easy to write actual tests and to interpret results
of failing ones.

This is a proof-of-concept right now; only a small number of
tests, by no means comprehensive. I am requesting review in
order to find showstopper problems: reasons why this approach
cannot work. Should there be none, we can work toward running
these as gating tests for Fedora and RHEL8.
