2.6.1 fix plu brydenf
Fixes to certain issues in the NSD Management test suite:
- Typos
- Set Headers called twice in a row with same attribute, discarding first call, fixing #120 (closed)
- Replaced RESTInstance Library calls with Requests library when non-JSON data was needed in the payload (plain/text, application/yaml, application/zip)
- An extra '../' was removed from the 'MOCK_SERVER_JAR' variable
