core: more efficient query for getting vms to monitor

Once in every 5th iteration (currently every 15 secs) we query all the VMs that
run on a given host for the sake of monitoring. We used to query them using the
'vms' view. 'vms' view get all the data of the VMs from vm_static, vm_dynamic,
vm_statistics, cluster, storage_pool, quota, vds_static, vm_pool_map_view and
snapshots, while the data needed by the monitoring resides only in vm_static,
vm_dynamic and vm_statistics.

This patch introduces another query dedicated for monitoring that is much
more efficient than the previous one.
