mgr/cephadm: refine log message

Avoid a lot of these

2020-03-13T14:58:38.785360-0500 mgr.x [INF] No data_devices, skipping DriveGroup: osd.all

every time we consider the OSD spec and find nothing to do.  Instead, log
something like this each time we actually have work to do:

2020-03-13T15:04:22.803356-0500 mgr.x [INF] Applying osd.all on host gnit...
2020-03-13T15:04:33.723731-0500 mgr.x [INF] Deploying daemon osd.5 on gnit
