system tests: podman-remote, image tree

[edsantiago]

• new sanity checks for podman-remote:

  • first, confirm that when PODMAN is "-remote",
    we actually talk to a server (validated by
    presence of "Server:" string in "podman version").
  • second, add test for Refactor parsing to not require --remote to be first flag #7212, in which we run
    "podman --remote" (podman with --remote flag,
    not podman-remote command) and make sure --remote
    is allowed both as the first option and also
    with other flag options preceding.

• new test for "podman image tree" (piggybacking on
  top of a "podman build" test, because that gives
  us lots of layers).

Restarted fedora-32, it's the cgroup.freeze flake (#7148)

Seeing a huge number of #7241 flakes. I'm just trying to gather data right now.

[edsantiago]

Tests green. I added a skip for one particular test that is triggering #7241 in CI, and causing pretty much every PR to fail CI. If we merge this, then rebase every PR, I think we'll be able to move on.
