Separate technical types from Data Structure

[dtrzesniak]

Currently, the whole model is there and it's becoming too complex.
We should refactor the file and separate the concerns.
Especially the technical types, like KeyedRecord and so on

I would like to have:

• business content separated from technical
• generic separated from specific (reporting node is generic, while liability type is specific --> where is the line?)
• dimensions/parameters/args/poco/identities types --> how do we want to group these? I would prefer to have those types that are not stored separated is a group separated from things like args and identities. data/poco types maybe too --> let's discuss.
