Fix handling of remove of bogus volumes, networks and Pods

In podman containers rm and podman images rm, the commands
exit with error code 1 if the object does not exists.

This PR implements similar functionality to volumes, networks, and Pods.

Similarly if volumes or Networks are in use by other containers, and return
exit code 2.
