adopt: stop iscsi services in the first place

If old containers are still running, it can make tcmu-runner process unable to open devices and there's nothing else to do than restarting the container. Also, as per discussion with iscsi experts, iscsi should be migrated before OSDs. (the client should be closed before the server) Closes: https://bugzilla.redhat.com/show_bug.cgi?id=2000412 Signed-off-by: Guillaume Abrioux <gabrioux@redhat.com> (cherry picked from commit d12efa1)
