IMPALA-6456: Add flags to configure rpc_negotiation_timeout_ms and ne…
…gotiation thread count in KRPC
With the fix for KUDU-2228, the FLAGS_rpc_negotiation_timeout_ms was
retired in KRPC.
This patch introduces a flag to be able to configure that from the
Impala side (FLAGS_rpc_negotiation_timeout_ms).
It also introduces a flag to configure the negotiation
thread count (FLAGS_rpc_negotiation_thread_count).
Added a test to verify that setting FLAGS_rpc_negotiation_timeout_ms
to 0 causes negotiation failures. We unfortunately can't write a test
to check the same for FLAGS_rpc_negotiation_thread_count due to
DCHECKS present in the code.
