[WIP] IMPALA-10811 RPC to submit query getting stuck for AWS NLB forever

This patch addresses Impala client hang due to AWS network load balancer
timeout. The scope of the fix applies to the following Impala clients.

  1. HS2
  2. Beeswax
  3. Impyla
  4. HUE

These clients issue thrift RPC ExecuteStatement() followed by repeated
call to GetOperationStatus() (HS2, Impyla and HUE) or a variant of it
(Beeswax) to Impala backend.

In the fix, the backend operation for ExecuteStatement() runs
asynchronously in a new thread and its completion status is checked
periodically via the equivalent of the GetOperationStatus() from the
client. A new execution state CATALOG_OP_RUNNING is added to represent
the new execution state.
