Expose informations of the libvirt storage volumes, either for one or
all the volumes. Among the provided data, this function exposes the
names of the virtual machines using the volumes of file type.
All users to remove a libvirt storage volume.
It may happen on pools that have not refresh for a long time that the
volume list is not matching reality. Then when calling the info() or
XMLDesc() functions libvirt errors out.

virt.volume_info() now handles this case.
Since the pool and volume parameters can be None, make them optional and
default to None.
Even though the volume_infos handles the libvirt exception when a volume
is missing, libvirt was still outputting the error message in the log.
Since this can add noise to the log only record the libvirt error
message in debug level.
libvirt raises an error when getting the list of volumes of a pool that
is not active. Rule out those pools from virt.volume_infos since we
still need to give infos on the other pools' volumes.
_get_domain returns a domain object when only one VM has been found.
virt.volume_infos needs to take care of it or it will fail to list the
volumes informations if the host in such a case.
virt._get_domain() throws an CommandExecutionError if there is no
virtual machine. In volume_infos() this is not an error at all since the
VMs list is only used to find out which VM uses each volume.
