Revert 60c8ba47e4dee05305d2c9ff68f57d91aabbbdc6 as contrail-api/ifmap fate share still.

If contrail-api is stopped after advertising ifmap to discovery, further updates
received by other api-servers is not reflected to local ifmap server.
If control-nodes are connected to this ifmap server they never get
these updates.

1. Increase the receive buffer for protobuf udp server to 32k to
   accomodate fabric_message sent from MX
2. Include the protobuf message name in the message statistics in
   addition to the endpoint name
3. Add a GetReceivedMessageStatistics() function that returns just
   the received protobuf message stats without doing a diff with
   the old received message stats

Without any filters, when a classic user tries to list the
security-group-rules from a config-api server which has
