As part of this, rework the number of workers used by various
Podman tasks to match original behavior - need an explicit
fallthrough in the switch statement for that block to work as
expected.
Also, trivial change to Podman cleanup to work on initialized
containers - we need to reset to a different state after cleaning
up the OCI runtime.
