Add logic for instance name

Currently the instance name can only consist of descriptors / static values. The usage of text in this context is nearly not usable for us, since our applications are used simultaneously by many users in different languages.

We would like to have the following additional options (sorted from high to low priority):

• Use global value list for key -> value mappings (including translations)

• Usage of translatable strings

• Use additional logic (e.g. if descriptor is not null use this descriptor, else use another descriptor)
