Fix: Streaming Backend Websocket DS provisioning (#341)

* chore(repo): add empty tsconfig.json so VScode doesn't choke when opening the project

* fix(ds-streambkend-websocket): provide valid datasource provisioning

* test(ds-streambkend-websocket): add e2e test to validate provisioning works out the box
