wzhou-code 8e350d0a8a IMPALA-11304: impala-shell make the client retry attempts configurable ...

Currently max tries for connecting to coordinator is hard coded to 4
in hs2-http mode. It's required to make the max tries when connecting
to coordinator a configurable option, especially in the environment
where coordinator is started slowly.

This patch added support for configurable max tries in hs2-http mode
using the new impala-shell config option '--connect_max_tries'.
The default value of '--connect_max_tries' is set to 4.

Testing:
 - Ran e2e shell tests.
 - Ran impala-shell with connect_max_tries as 100 before starting
   impala coordinator daemon, verified that impala-shell connects to
   coordinator after coordinator daemon was started.
