Invalidate network info cache in periodic task

This is meant to be done in _heal_instance_info_cache() periodic
task, but the problem with it is that, if network info cache gets
corrupted due to a race condition, it won't ever be 'healed' again
as we use corrupted info to refresh the cache.

The idea here is to go to Neutron in _heal_instance_info_cache() and
get latest data to update our local cache.
