MXS-1600: Add case-insensitive matching to MySQLAuth

Browse Source 
The authenticator now supports similar identifier matching as the MariaDB
server. The lower_case_table_names parameter explains its intended use
(case-insensitive identifier matching):

### `lower_case_table_names`
Enable case-insensitive identifier matching for authentication. This parameter
is disabled by default.
The parameter functions exactly as the MariaDB Server system variable
[lower_case_table_names](https://mariadb.com/kb/en/library/server-system-variables/#lower_case_table_names).
This makes the matching done by the authenticator on database names to be
case-insensitive by converting all names into their lowercase form.
**Note:** The identifier names are converted using an ASCII-only function. This
means that non-ASCII characters will retain their case-sensitivity.
