Add support to configure VF queue rate limit and quanta size. For quanta size configuration, the quanta profiles are divided evenly by PF numbers. For each port, the first quanta profile is reserved for default. When VF is asked to set queue quanta size, PF will search for an available profile, change the fields and assigned this profile to the queue.
