Abhishek Rawat 8e755e7571 IMPALA-11126: impala-shell: Support configurable socket timeout for http ...

client

In 'hs2-http' mode, the socket timeout is None, which could cause
hang like symptoms in case of a problematic remote server.

Added support for configurable socket timeout using the new impala-shell
config option '--http_socket_timeout_s'. If a reasonable timeout is
set, impala-shell client can retry in case of connection issues, when
possible. The default value of '--http_socket_timeout_s' is set to None,
to prevent behavior changes for existing clients.

More details on socket timeout here:
https://docs.python.org/3/library/socket.html#socket-timeouts

Testing:
- Added tests for various timeout values in test_shell_commandline.py
- Ran e2e shell tests.
