Public bug reported:
The notify_usage_exist() function always query the DB to get the
bandwidth usage data. But such data is only available if the
CONF.bandwidth_poll_interval is set to a positive number (600 is the
default) and the virt driver supports such data collection. Today only
xenapi driver supports this data collection. So it would make sense to
avoid the DB query when it is known that such data is not available.
