[Automotive] QtIVI BackendType Switch/Registration

Hi all,

Working with the Qt Automotive Suite, running QtApplicationManager and
using QtIVI.

I'm currently working to implement the structure for switching the backends
and I was curious if anyone had actually tried to do this yet.

The documentation on this is very light and the behavior I'm experiencing
feels counter intuitive.

It seems that the "Simulator Plugin" in the QtIvi repository (and any
installed service interfaces) is being registered as a Production backend
by default and there seems to be no obvious way to tell the dynamic loader
to switch to Simulation Backend type.

The system seems to be setup such that I shouldn't need to manually operate
the QIviServiceManager, however, as I'm investigating this backend
switching functionality, it seems that I will have to in order to get the
behavior I want.

I feel like, in this example in QtIvi of the vehiclefunction_simulator
plugin, I should be able to declare the object is a SimulationBackend.

It would be great to hear if I'm missing something obvious, but either way
I appreciate any feedback.

Thanks!
Best Regards,
