Change subject: IMPALA-3875: Set thrift socket timeout before any connection
......................................................................
Patch Set 1:
Without this patch, query stucks at
Query Timeline: 4h38m
- Start execution: 0.000ns (0.000ns)
- Planning finished: 531.006ms (531.006ms)

- Completed admission: 532.006ms (0.000ns)
- Ready to start 2 remote fragments: 533.006ms (1.000ms)
forever.
With this patch, ~10mins (not sure why so long, the setting was 5mins. I
attached gdb in the process but that cannot explain all), the query gets
timeout as expected:
Query (id=184d56eb52842360:9a421d4cfd42a8ad):

There are more things need to be done in this patch... but I think we have to
add timeout to all Thrift transport.
