Feature/sapna canvas course creation

Added controller logic to make get course information and add a section. Added SDK settings to initiate SDK calls. Currently not using create course SDK call due to an issue with the use of reserved words in the courses calls.
I'm not sure we want this call to be part of the larger try/catch block.  Rather, we should be handling an ObjectDoesNotExist exception here (or a CourseData.DoesNotExist) and raising an Http404.
