Reconsider broad usage of interfaces

[Toxantron]

Is your feature request related to a problem? Please describe.
We are currently using interfaces excessively, even for Configs, DTOs or domain model objects. However when it comes to versioning extending an interface is breaking, extending a class a minor. And in many cases we don't even support other implementations as we often have a mandatory base class implementation.

Describe the solution you'd like
I recommend limiting interfaces from now on and declaring any unnessary ones as deprecated. In case of deprecated interfaces we should make future extensions to the class only to encourage users to switch and ease future removal of those interfaces.

Additional context
This issue will remain open and can be referenced by any commits that deprecate interfaces.

From @Toxantron in #239

Extend interface for IAxesController to include multiple axes in a single call, include ITransportSystem to reuse the API outside the control system.

Points for discussion

• Do we really need a driver for a weight scale? Couldn't this be represented as IInputDriver<double>
• Do we need a scanner driver or could they be reduced to IInputDriver<string> or at least be combined with RfidAntenna?
• IAxesController should accept arrays of instructions, for moving multiple axes at once
• ITransportSystem should be moved here for manufacturing and logistics control

Also consider

• IProductType
• IProductPartLink and IProductPartLink<TProduct>
  At the moment, the ProductConverter implementation assumes all ProductTypes to only have properties using the generic interface IProductPartLink<TProduct> when generating the ProductModel for the UI here
