rate-limiter: add rate limiter configuration/annotation on VM level

Browse Source 
Add configuration/annotation about network I/O throttling on VM level.
rx_rate_limiter_max_rate is dedicated to control network inbound
bandwidth per pod.
tx_rate_limiter_max_rate is dedicated to control network outbound
bandwidth per pod.
