Subject: [PATCH] ceph-daemon: only pass podman -it if need an interactive
 shell

Otherwise, we get errors like

2019-10-26T17:29:42.004 INFO:tasks.workunit.client.0.mira109.stderr:+ sudo /usr/sbin/ceph-daemon shell -- ceph -v
2019-10-26T17:29:42.004 INFO:tasks.workunit.client.0.mira109.stderr:+ grep 'ceph version'
2019-10-26T17:29:42.149 INFO:tasks.workunit.client.0.mira109.stderr:the input device is not a TTY

Fixes: https://tracker.ceph.com/issues/42499
