Description
The DataNodes should rate-limit their full block reports. They can do this by first sending a heartbeat message to the NN with an optional boolean set which requests permission to send a full block report. If the NN responds with another optional boolean set, the DN will send an FBR... if not, it will wait until later. This can be done compatibly with optional fields.
