RDS: Stop supporting old cong map sending method
We now ask the transport to give us a rm for the congestion map, and then we handle it normally. Previously, the transport defined a function that we would call to send a congestion map. Convert TCP and loop transports to new cong map method. Signed-off-by: Andy Grover <andy.grover@oracle.com>
