contrail-schema: recreate_vrf_assign_table is called for every config update. Keeps API server busy

[Prakash Bailkeri]

For every ifmap notification, contrail-schema performs recreate_vrf_assign_table. This function walks through all the VMI in the system(does more API server READ for Service instance VMs VMI) to check whether VRF assign table needs to be (re)built.

If the setup has more service instances running and has more VMIs, since it is triggered on every config update, it keeps API server busy(Also seen timeout for API server requests)
