shrink-osd: fix purge osd on containerized deployment
shrink-osd: fix purge osd on containerized deployment

ce1dd8d introduced the purge osd on containers but it was incorrect.

`resolve parent device` and `zap ceph osd disks` tasks must be delegated to
their respective OSD nodes.
Indeed, they were run on the ansible node, it means it was trying to
resolve parent devices from this node where it should be done on OSD
nodes.
