DiskList: render osdid-list if present

DiskList: render osdid-list if present

Render all OSD IDs in 'osdid-list' if the parameter is present.

It is possible to have multiple OSD daemons on a disk. We want to list
them all in the UI.
Fall back to the 'osdid' parameter if 'osdid-list' is not available.

We check rec.data['osdid-list'] against its general truthiness as it
might not be present at all or null.
