Test for the Containerfile does not attempt to use skstat/skmanage, misses issues with Proton Python install

@jiridanek this issue seems to have been fixed by you already. Close this issue ?

@ganeshmurthy The job still does not check that skstat/skmanage run, so there is more work to do. (They do run now, but it is not tested there.)

One additional problem; the test does not wait for router to start and open port, so if it starts slowly, test fails. This is also something to be solved here.

See HEALTHCHECK Containerfile instruction, https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/building_running_and_managing_containers/assembly_monitoring-containers_building-running-and-managing-containers#performing-a-health-check-using-a-containerfile_assembly_monitoring-containers

Healthcheck feature is present in the router, 1e22255 hopefully it does what I need it to do (claim Healthy only when all listeners declared in config were opened).
