Riza Suminto 09d2f10f4d IMPALA-13040: Add waiting mechanism in UpdateFilterFromRemote ...

It is possible to have UpdateFilterFromRemote RPC arrive to an impalad
executor before QueryState of the destination query is created or
complete initialization. This patch add wait mechanism in
UpdateFilterFromRemote RPC endpoint to wait for few miliseconds until
QueryState exist and complete initialization.

The wait time is fixed at 500ms, with exponential sleep period in
between. If wait time passed and QueryState still not found or
initialized, UpdateFilterFromRemote RPC is deemed fail and query
execution move on without complete filter.

Testing:
- Add BE tests in network-util-test.cc
- Add test_runtime_filter_aggregation.py::TestLateQueryStateInit
- Pass exhastive runs of test_runtime_filter_aggregation.py,
  test_query_live.py, and test_query_log.py
