Inheritance is not well defined in openBIS #229
Description
When accepting the changes from @CagtayFabry to add some property in INSTRUMENT, I realized a thing: inheritance in openBIS object type definitions is not well-defined, meaning (for this particular example) that not all properties of INSTRUMENT are inherited by its child objects (e.g., check INSTRUMENT.MEASURING_AMPLIFIER).
I guess this is some historical issue. But in short: if something is a subtype (inherits) from another concept, it is also copying its properties.
In the future, this will change, so for now I will directly push this into the backlog, but it affects the new objects when we define them.
