[ARTMIS-1431] Adapt transport configuration in ClientProtocolManagerFactory

add the adaptTransportConfiguration() method to the
ClientProtocolManagerFactory so that transport configurations used by
the ClientProtocolManager have an opportunity to adapt their transport
configuration.

This allows the HornetQClientProtocolManagerFactory to adapt the
transport configuration received by remote HornetQ broker to replace the
HornetQ-based NettyConnectorFactory by the Artemis-based one.
