Title: position of user in completions and course avg

@mattdrayer @martynjames added new api to get position of user in a course in terms of course module completions and course average completions. It'll return a JSON like this
`
{
"position": 4,
"completions": 5,
"course_avg": 4.5
}
`
`position` is user's position among other users
`completions` is # of course modules completed by the user
`course_avg` is avg of course module completions in the course
