IMPALA-12411: Fix data race in expr-test teardown
TSAN ThreadSanitizer detected a data race during expr-test teardown. It
happens because ImpaladQueryExecutor closes the previous query when you
start the next query and it relies on the destructor to close the last
query.
expr-test creates ImpaladQueryExecutor as a global as part of setting up
an in-memory cluster (with Statestore and InProcessImpalaServer). So the
last query isn't guaranteed to be closed until global destruction, which
leads to a race with other global destruction (in this case with
JvmMetricCache while updating QueryState on query completion).
ImpaladQueryExecutor is only used in expr-test.
