Upgrades the impala-shell's bundled version of sqlparse to 0.3.1. There were some API changes in 0.2.0+ that required a re-write of the StripLeadingCommentFilter in impala_shell.py. A slight perf optimization was also added to avoid using the filter altogether if no leading comment is readily discernible. As 0.1.19 was the last version of sqlparse to support python 2.6, this patch also breaks Impala's compatibility with python 2.6. No new tests were added, but all existing tests passed without modification.
