Have federation configuration respect extra url parameters from the connector-ref

a connector ref with a url of the form:
"tcp://localhost:61616?ackBatchSize=100&consumerWindowSize=-1"

should be capable of configuring the ServerLocator used by a federation client.
These are ignored by the transport connector but are captured as extraParameters in the internal configuration.
It is simply a case of applying them. currently they are ignored!
This is better than duplicating additional serverLocator configuration in federation configuration.
