Some customer is asking for API usage endpoint so that they can monitor their API usage per account.
Bitbucket users may sometimes exceed our API limits, however they have no way to see which endpoints are mostly used, unless they contact support.
It is also not possible for them to see how many requests they have left for the coming hour.
Provide a way to users to see
(a) which API calls have been made by their user for a certain time frame
(b) how many calls are left before they hit our limit
