bindinfo: correctly handle quotes for bindings sql

[alivxxx]

What problem does this PR solve?

mysql> create global binding for select * from t where a = '1' using select * from t use index(idx) where a = '1';
[2019/11/04 14:59:18.561 +08:00] [WARN] [session.go:1078] ["parse SQL failed"] [error="line 1 column 111 near \"1'', 'test', 'using', '2019-11-04 14:58:22.461', '2019-11-04 14:58:22.461','utf8mb4', 'utf8mb4_unicode_ci')\" "] [SQL="INSERT INTO mysql.bind_info VALUES ('select * from t where a = ?', 'select * from t use index(idx) where a = '1'', 'test', 'using', '2019-11-04 14:58:22.461', '2019-11-04 14:58:22.461','utf8mb4', 'utf8mb4_unicode_ci')"]

What is changed and how it works?

The quote is not correctly handled, the result sql cannot be parsed by tidb. This PR reuses the quote function logic to handle this case.
