The podman-login tests have accumulated much cruft over the
years, because that's the only place where we run a local
registry, and the process was crufty: we actually start/stopped
the registry as the first & last tests of the file. Meaning,
you couldn't do 'hack/bats 150:just-one-test' because that
would skip the registry start. And just now, a completely
unrelated test has had to be shoved into the login file.
This PR revamps the whole thing, by adding a new registry helper
module that can be used anywhere. And, once the registry is
started, it just stays running until the end of tests. (This
requires BATS 1.7 or greater).
