In preperation for removing the Client annotation from ServiceProvider this passes a second parameter of type ServiceProvider in the shell and application Connect calls. In this patch the type signatures are updated but the second parameter is basically unused. The intention is that the first parameter |services| will be used for the connecting application to request services from the connected application (as it does currently) and the second parameter |exported_services| be used for the connecting application to provide services to the connected application. We have very few services exported in the second direction today - I'll update them to use the second parameter in a follow-up patch.
