[Users] Excessive syslog logging from vdsm/sampling.py

[Sander Grendelman]

The "not assigned to domain"-errors appear to be for thin provisioned disks
and for snapshots (which are also shown as thin provisioned by the engine).

One of the errors has gone away once I removed all snapshots from the VM.

Three recurring errors remain:

[root at gnkvm02 ~]# tail -n 1000 /var/log/messages | awk '/not assigned to
domain/ {print $8}' | sort | uniq -c
    333

[root at gnkvm02 ~]#

The first two are for the two thin provisioned disks of a VM with three
disks.
The last one is for a VM with one preallocated disk which has a snapshot.

The syslog is spammed every two seconds by these three messages.
