Lots of write timeouts and missing data during decomission/bootstrap

We get lots of write timeouts when we decommission a node. About 80% of them are write timeout and just about 20% of them are read timeout. We’ve tried to adjust streamthroughput (and compaction throughput) for that matter and that doesn’t resolve the issue. We’ve increased write_request_timeout
