Description
Allow a node to receive writes (which are relatively cheap) but not reads (random io). The purpose is to allow a major compaction or repair to be run on a node that is under too much load for this be safely done "live". Marking a node as down by disabling gossip is good enough in some cases(for major compaction). But for repairs is insufficient, since hints will build back up once I repeat the process on the next node.
This is presumably a rather complicated change in to gossip to accommodate the new state. I am also concerned of the effects of having different numbers of nodes available for write and read quorums.
