feat(tcs-huawei-socketio): remove deprecated connector

- Remove `cactus-plugin-ledger-connector-tcs-huawei-socketio` connector and
  any reference to it.
- This is not permanent - we'd love to bring the package back once the
    necessary refactors are done!
- See issue #3155 on github for more details on context and reasoning
    of this decision.

Part of #3155
