Feature Request

For any get-by-id DSP request (namely dataset request, contract negotiation request, transfer process request) we're using the GetDspRequest class to pass all required information to the protocol service. This class currently expects a string (the id) as input, as previously there were no RemoteMessage implementations for getting a negotiation or a transfer process.

In this PR, these missing RemoteMessage implementations have been added. The GetDspRequest can therefore be refactored to accept a RemoteMessage, which passes both id and protocol information to the service.
