/**
* Utility to parse the config uri string.
*
* tuscany:[domainName]?listen=[port|ip:port]]&password=abc&multicast=[off|port|ip:port]&remotes=ip:port,ip:port,...
* listen - defines the local bind address and port, it defaults to all network interfaces on port 14820 and if that port in use it will try incrementing by one till a free port is found.
* password - is the password other nodes must use to connect to this domain. The default is 'tuscany'.
* multicast - defines if multicast discovery is used and if so what multicast ip group and port is used.
* The default is multicast is off if remotes= is specified (only for now due to a Hazelcast limitation that is planned to be fixed),
* otherwise if remotes= is not specified then multicast defaults to 224.5.12.10:51482
* remotes - a list of ipAddress:port for remote nodes
