David Knupp c26e3db4bd IMPALA-9362: Upgrade sqlparse 0.1.19 -> 0.3.1 ...

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.
