Salvatore Orlando 2bfa1d45b4 Introduce periodic state synchronization with backend
Blueprint nicira-plugin-get-improvements

With this patch GET operations on the Nicira plugin will not
be forwarded anymore to the NVP backend.
Resource operational status will be periodically retrieved from
the NVP backend using a DynamicLoopingCall.
The process has been designed with the aim of avoiding:
1) frequent queries to NVP for retrieving resource status
2) execution of large queries to NVP for retrieving the status
   of a consistent number of resources.
The process can be tuned using a set of configuration variables.
GET operations will now return a status which might differ
from the actual status of the resource. For retrieving status
in a punctual way, the field 'status' should be explicitly
specified in the GET request (only 'show' support has been
implemented in this patch)

This patchs also makes some changes to the fake nvp api client in
order to ensure each instance has a private set of dictionaries for
fake nvp entities.
