Enable ebike demo
Added datacollector, which is generates mock data to the demo.
It needs to be configured to run as a service or manually started
before running the demo. Without running datacollector, the demo
does not show any changing data.
Task-number: QTBUG-67917
Change-Id: Ia113b76b5eb024353051b93d9d518211ee2cd601
