IMPALA-7467: Port ExecQueryFInstances to krpc
This patch ports the ExecQueryFInstances rpc to use KRPC. The
parameters for this call contain a huge number of Thrift structs
(eg. everything related to TPlanNode and TExpr), so to avoid
converting all of these to protobuf and the resulting effect that
would have on the FE and catalog, this patch stores most of the
parameters in a sidecar (in particular the TQueryCtx,
TPlanFragmentCtx's, and TPlanFragmentInstanceCtx's).
Testing:
- Passed a full exhaustive run on the minicluster.
Set up a ten node cluster with tpch 500:
- Ran perf tests: 3 iterations per tpch query, 4 concurrent streams,
no perf change.
- Ran the stress test for 1000 queries, passed.
