Bug Description

Currently contrail-vrouter hard codes Rx queue number to 11, that means it only can support 11 cpu cores per current forwarding threads model. But in many user scenarios, people want to assign more than 11 cores to contrail-vrouter, current contrail-vrouter can't handle this.

Change the default number of rx queues to 16

Current default number of rx queues is 11, that is not enough
if we assign more than 11 cores to vrouter fwd threads.
