Add management of stale issues (#2279)

Add new policies for Microsoft Github bot to auto close issues that
needs-author-feedback and don't get reply.

- 7 Days without author feedback will send a reminder
- 14 days without author feedback will close the issue
- Response from the author will remove the `needs-author-feedback`
