Graph Store HTTP Protocol (GET, POST) back end

[Qup42]

Implement a function transformGraphStoreProtocol that does the back end of transforming a SPARQL Graph Store HTTP Protocol request to it's equivalent SPARQL Query or Update. The integration will be a separate step.

TODO:

• think about function definition in header

Additional smaller changes that were required or sensible and which could be extracted into separate PRs if needed:

• move checkParameter from Server to ad_utility::url_parser
• extract creation of test HTTP request into HttpRequestHelper
• add methods to access Id from TripleComponent
• added media types N-Triples and N-Quads
