This commit adds a method to the database connector which allows the retrieval of linked documents
from couchdb as described in http://docs.couchdb.org/en/2.1.0/ddocs/views/joins.html.

Read the documentation for the annotations LinkedDocument and LinkedDocuments as well as the
test cases in LinkedDocumentLoadingTest for more information about how it works.

This POC sadly fails if the list of linkedReleaseIds is empty (see the committed test).

note that we preserved state here:

I think we can solve this for now since this has not been discussed since a longer time
