[COMMON] Allow to use ' in mysql passwords
derivePassword which we use to generate our passwords includes ' in set of special characters that can be used in passwords. Current implementation of bitnami configure-mysql.sh simply concatenates password surrounded with '' rest of SQL query. This causes issues if password contains ' as it creates invalid SQL statement. To fix this issue we just patch the script and escape the special ' character in password.
