Proposed Extension: SHACL

To wrap up what I have been doing with SHACL as well as discussions with @alien-mcl I would propose a SHACL+Hydra extension comprising of two independent parts:

[ ] Using SHACL as a more flexible tool for describing request models (https://github.com/HydraCG/Specifications/issues/214, https://github.com/HydraCG/Specifications/issues/215)
[ ] Describing Hydra Core terms in SHACL Node Shapes
