{create,run} --replace

Browse Source 
Add a `--replace` flag to the `container {create,run}` commands.
If another container with the same name already exists, it will
be replaced and removed.

Adding this flag is motivated by #5485 to make running Podman in systemd
units (or any other scripts/automation) more robust.  In case of a
crash, a container may not be removed by a sytemd unit anymore.  The
`--replace` flag allows for supporting crashes.
