Add more Probots

We're already using the stale bot which seems to work quite well for us.
Let's also add:

- [No Response](https://probot.github.io/apps/no-response/) (replacing
[github-snooze-button](https://github.com/tdsmith/github-snooze-button))
- [Move Issues](https://probot.github.io/apps/move/)
- [Support Requests](https://probot.github.io/apps/support/)
- [Lock Threads](https://probot.github.io/apps/lock/)
