Add MariaDB URL Parser to List of ConnectionInfo Parsers

[jayeve]

Problem When using MariaDB url with this library, the ConnectionInfo always shows up as UNKNOWN_CONNECTION_INFO.

Solution This adds a MariadbURLParser class to the map of registered url parsers. The implementation of this parser is effectively piggybacking off the implementation of the MysqlURLParser because the maria URLs are built to be compatible with mysql URLs. the connecting string structure:

jdbc:(mysql|mariadb):[replication:|failover:|sequential:|aurora:]//<hostDescription>[,<hostDescription>...]/[database][?<key1>=<value1>[&<key2>=<value2>]]
