Do not attempt to manage collocated Ceph containers

If an HCI EDPM node has Ceph containers, then they
should not be be manged by the edpm_container_manage
role. Add a new task to exclude Ceph containers from
the list of containers built by the call to
containers.podman.podman_container_info.

Without this new task, the edpm_container_manage role
delete_orphan.yml tasks file attempts to process Ceph
containers but it cannot handle them so it fails with
an AttributeError: 'NoneType' object has no attribute
'get'.
