Put Rate Limit related data into response for REST API calls

That's a great idea, too.  I've been fiddling with it for about an hour - it actually wasn't too hard to update my LM api call function to use invoke-webrequest, output the content as json, implement a check to avoid get rate limited - so may be moot for me now.  But I can imagine if people have PS scripts out there and haven't created functions/libraries for their api calls this would be a bigger headache.
