Make the inst-status-xen collector more resilient

The data collectors should be able to provide as much information as possible
even when the system is badly degraded. This patch modifies the instance status
collector for xen so that it can keep providing as much data as possible, even...

Include "instance" information in LV data collector

This commit enables the logical volume data collector to get information about
the instances and to link it to the information about logical volumes.

Factor out lv info gathering function

The buildJsonReport function will soon have to perform the coupling of
instance data with LVInfo data. In preparation for that, in order to make
it more readable, the instructions for obtaining LVInfos are factored out...

Factor out the getInstances function

a proper (newly created) library.

lvCommand is a surely non-empty list, but the compiler still refuses it
asking for explicitly management of the empty list case....

python code base earlier this quarter. We generalize the
name, because we needed a place for general storage...
