IMPALA-6337: Fix infinite loop in Impala shell
This patch fixes a bug in sqlparse where sqlparse incorrectly splits a
statement that has a new line inside double quotes. The bug in sqlparse
causes Impala shell to go to infinite loop when a statement contains a
new line inside double quotes.
The patch in sqlparse is based on the upstream fix at
https://github.com/andialbrecht/sqlparse/pull/396
Testing:
- Added new end-to-end shell tests
- Ran end-to-end shell tests
