Similar to how a JDBC URL works, providing a convenient format for 
specifying a connection to an Infinispan resource.
Look at [1]

The use of the ?name=value[&name=value] format in the URL is not the 
only way. JDBC, for example, has a separate properties param:

DriverManager.getConnection(jdbcUrl, properties);

This is not for connecting to an existing instance, but for actually 
creating a cachemanager.
