Currently working with the API's for drive, graph, sharepoint are very difficult due to the throttling that can be encountered.

Each api offers different guidance to avoid throttling. Example are:
1) use a special user-agent header
2) respect the retry-after header

Speaking with microsoft representatives they instruct us to perform major api processing in off peak hours. Additionally tenant's can have hard locks placed on them.

This request is to get better information around tenant usage returned in the API's.

1) If a tenant is hard locked, tell us in a distinct message so that don't just hammer the requests over and over again.
2) Give us feedback in our api calls regarding the health of a tenant. If we are approaching a threshold limit, give us some type of header we can use to instruct us to slow down our requests.
