Lazy Metadata Loading in order to Reduce Server Load

Registered by Fabian Wiesel

When a user request data from the metadata server, it will query Neutron for
all related ports and nova internally for all related data which potentially could
queried. The request often only requires a subset of the data.The existing
caching mechanism has no cache invalidation, therefor only allows a
trade-off with accuracy.
