feat(cactus-plugin-ledger-connector-fabric-socketio): remove fabric-socketio connector

- Remove cactus-plugin-ledger-connector-fabric-socketio connector.
- Refactor discounted cartrade sample to use openapi fabric connector instead of fabric-socketio.
    Sample app will use delegated signing, similar to offline signing in old connector.
- Remove dead code from cmd-socketio-server
- Update fabric SDK to 2.X in all cacti projects, refactor code that use it where necessary.
    Only exception is fabric persistence plugin which uses fabric SDK as dev dependency (for tests).
    It can be updated in separate PR later on.

+#### Possible improvements
+- Ethereum events are duplicated, causing trade to proceed even if previous step was not successfull.
+   - Handle this case properly - ignore duplciated events, move forward only if current step was completed.
+   - Investigate and fix duplicated events in Verifier / Ethereum connector (or use openapi ethereum connector).
