as an SDC user,

I want to separate the different data model types into folders.

so that there will be a clear separation of the models

DOD:

1. in the normative we should have 5 folders:
   1. normative and heat types
   2. nfv for the volte types (before change onap)
   3. SOL types
   4. and onap types
2. the import of the types should be triggered only by the import onap types.
3. the types will not be dependent on types from different folders.
4. post merge - normative alignment
