Multiprotocol DSP path

[wolf4ood]

Feature Request

Currently for out going messages a connector takes the counterPartyAddress and append the path based on the chosen dsp protocol version which is configured in the connector. This might not be the case when communicating with a different dsp implementation which might expose protocol version under different paths.

Since EDC now expose the management api for fetching supported DSP version from a counter party we should let the users decide the base path of the dsp version (counterPartyAddress + dsp version path) directly in input, without automatically infer that.

Meanwhile for the callbackAddress which currently comes from ProtocolWebhook should automatically infer and append ther dsp version path based on the connector supported version in the ProtocolVersionRegistry

To keep the current behavior we might introduce a configuration flag which should be disable by default.

Which Areas Would Be Affected?
