progress: auto-select progress based on the environment

[mvo5]

This commit adds automatic progress bar selection based on checking
if we run on a terminal or not. When running on a terminal we use
the nice "terminalProgressBar". If that is not set we assuem
we run in a script or CI/CD environment and select plainProgressBar.

Thanks Colin for the hint about the bad integration test.

Ideally we would check for a terminal but with podman we never have one.

docker/podman run -t ?

See also https://github.com/containers/podman-bootc/pull/61/files#diff-000666f7f8953356d352cfc7388aac26f46bb3f75ef9f413b8908a7bf8eb2729R352

which was motivated by bootc having progress too.

(And that relates to the larger overlap/duplication/desire-to-bridge between bootc progress and osbuild progress in containers/bootc#921 (comment) )

Thanks!

Uh, that is rather embarrassing, I may indeed have just written my integration test incorrectly (had forgoten about -t) . I'm an idiot. Well, I guess it's good, it makes things easier.

pylint seems to be complaining in the integration tests. Can you take a look, Michael?
