Description

--config_file in Impala shell uses "dest" variable names and not flag names due to: https://github.com/apache/impala/blob/master/shell/option_parser.py#L132

This is confusing because the users may not know what the dest variable names are without looking at the Impala shell source code. We should either make the dest variable names the same as flag names or modify the Impala shell code to use the flag names.
