API for Orders API Loader in Connect

[rwestbrock]

We have a use case where we modify prices on existing subscriptions by importing a file using the Orders API Loader in Connect. In order to automate this process we would like to see an API exposed where we can pass the CSV file in the payload to create an import job.

The existing Orders APIs will not work for this use case because we have thousands (sometimes tens of thousands) of subscriptions to update. It would be much simpler to make one API call in this manner instead of writing our own tool that has to take API rate limiting into account.
