Introduce a new parammeter with bool value for each port:
1. mysql_require_secure_transport for mysql_port;
2. postgresql_require_secure_transport for postgresql_port.
When the parameter is set to 'true', connect to clickhouse server will fail
by mysql with "--ssl-mode=disabled" or psql with "sslmode=disabled".
