> 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.
