Harmonize domain properties

[flomickl]

What to change
by default, domainProperties are stored in an ArrayList

but some methods just allow creating domain properties as a single string input.
This has to be harmonized

1. Make sure that streamrequirement can read List<URI>
2. Harmonize all methods in EventPropertyPrimitive and extend input parameters from String domainProperty to List<URI>
3. change naming of domainProperty to semanticType
4. EventPropertiyPrimitiveBuilder extend .domainProperty(String domainProperty) to List
5. EpProperty Double, Integer, Number General, Boolean, Image has only a single string

Output should be something like the EpProperty.longEp with the parameters
(Label label, String runtimeName, List< URI> domainProperty)

In the end it is possible to add / read more than one semanticType

In the required Stream process, you can only ask for single String domainProperty in the methods

In the EventPropertyBuilder it is also just a single String

But some methods in the EpProperty have a List Options

@flomickl can you formulate an expected outcome? That would be great :)

@bossenti hope it is now easier to understand and the output clearer :)
