Introduce an optional rdfCollectionRepresentation attribute on ResourceProperties which can be set to rdfList or rdfBag (or n/a)

NOTE: This is what I have tested. But I have NOT tested that the actual annotation produces the expected result from JenaModelHelper.

• if set to "n_a", no affect on produced java code.

• if set on properties with cardinality 0..1 or 1: no effect on produced hava code.

• If set to "RDFBag" on a Property with a "many" cardinality:

  1. We add the @OslcRdfCollectionType(collectionType = OslcRdfCollectionType.RDF_BAG).
  2. The property is defined as Set/Hashset in the Java code.

• if set to "RDFList" on a Property with a "many" cardinality:

  1. We add the @OslcRdfCollectionType(collectionType = OslcRdfCollectionType.RDF_LIST).
  2. The property is defined as List/ArrayList in the Java code.

@berezovskyi Can you safely review this without me sharing Java generated code?

Ignore the commited java files (from EMF). Main logic is in the resourcePropertyServices.mtl file.

@nilsjor @berezovskyi Please review 2nd commit. I removed support for RDF:Bag. I also renamed "n_a" to "none". It was not easy to re-label the options to something more intuitive. I would rather do this for many other parameters at once.

@berezovskyi What do you think of this naming? Last offer.

Sounds good!
