> 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.
