casey 71c5ec7af5 IMPALA-1612: (shell) Upgrade sqlparse for bug fix
The only thing this commit does is upgrade sqlparse. The upgrade was
done by downloading and extracting the tarball, nothing else (such as
patching). The older version of sqlparse would parse

SELECT
'
;
'
;

into two statements. Neither statement is complete due to the open quote
and this would cause an infinite loop. The bug is already fixed in the
newest version of sqlparse.
