Subject: BATS and APIv2: more tests and tweaks

 - (minor): apiv2 tests: check for full ID

   Observation made while reviewing #6461: tests were checking
   only for a 12-character container/image ID in return value.
   It's actually 64, and we should test for that. This should
   also minimize confusion in a future maintainer.

 - podman pause/unpause: new test

   Runs a 'date/sleep' loop, pauses container, sleeps 3s,
   restarts, then confirms that there's a 3- to 6-second
   gap in the logs for the container.

 - podman healthcheck: new test

   run a container with healthcheck, test both healthy
   and unhealthy conditions

 - podman pod: check '{{.Pod}}' field in podman ps

   Hey, as long as we have a pod with two running
   containers, might as well confirm that 'podman ps'
   returns the expected pod ID.
