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.
We'll probably want to pull this out into a utils layer since the auth token should vary based on account_id.  I can see having a function that takes an account_id and returns a context, for example.  For the time being it could do what this line is doing (ignoring the account_id), but it would be a place to make the auth token changes necessary down the road.
