Changes

Implement the POST api/v1/courses/{course_id}/lms, which creates one record in the course_to_lms table.

Testing

• Test if it raises exception when course_id and lms_id are invalid;
• Test if it raises exception when external_course_id is missing.
• Test if it raises exception if this bind between such this course and lms exits before.
• Test if such a target record could be successfully created in the course_to_lms table.

#39 also has these changes. It would be great if you could remove this pr's code from the other one and resolve the comments I left on that one :)

Hi Connor, thanks for your comments! I've already made changes based on your comments on #39. Sorry for the inconvenience caused by the huge pr. Please let me know if I should make further modification on this feature branch, thanks!

generally OK, made a couple of minor comments, will leave final merge authority within the team since this is the golden repo, de facto.

Couple of comments, but overall looks good.
