Blacklist node if a DataStreamService RPC to the node fails

If a query fails because a RPC to a specific node failed, the query error message will similar to one of the following:

• ERROR: TransmitData() to 10.65.30.141:27000 failed: Network error: recv got EOF from 10.65.30.141:27000 (error 108)
• ERROR: TransmitData() to 10.65.29.251:27000 failed: Network error: recv error from 0.0.0.0:0: Transport endpoint is not connected (error 107)
• ERROR: TransmitData() to 10.65.26.254:27000 failed: Network error: Client connection negotiation failed: client connection to 10.65.26.254:27000: connect: Connection refused (error 111)
• ERROR: EndDataStream() to 127.0.0.1:27002 failed: Network error: recv error from 0.0.0.0:0: Transport endpoint is not connected (error 107)

RPCs are already retried, so it is likely that something is wrong with the target node. Perhaps it crashed or is so overloaded that it can't process RPC requests. In any case, the Impala Coordinator should blacklist the target of the failed RPC so that future queries don't fail with the same error.

If the node crashed, the statestore will eventually remove the failed node from the cluster as well. However, the statestore can take a while to detect a failed node because it has a long timeout. The issue is that queries can still fail in within the timeout window.

This is necessary for transparent query retries because if a node does crash, it will take too long for the statestore to remove the crashed node from the cluster. So any attempt at retrying a query will just fail.
