IMPALA-9384: Improve Impala shell usability by enabling live_progress in 
interactive mode

In order to improve usability, this patch would like to make Impala shell show 
query
processing status while the query is running. The patch enables shell option
live_progress by default when a user launches impala shell in the interactive 
mode.
The patch also provides a new command line flag "--disable_live_progress", 
which allows
a user to disable live_progress at runtime. In the interactive mode, a user can 
disable
live_progress by either using the proposed command line flag or setting the 
option as
False in the config file. As for in the non-interactive mode (when the -q or -f 
options
are used), live reporting is not supported. Impala-shell will disable 
live_progress if
the mode is detected.

Testing:
- Added and updated tests in test_shell_interactive.py and 
test_shell_commandline.py
- Successfully ran all shell related tests is detected.
