Minimum permission

The administrator does not need an extra permission on a device they bound. A shared device needs the basic configuration permission. A bound sub-user does not. A sub-account needs Config. Omitting channelId on a channel-scope capability returns DV2007. Mixing device and channel in one request returns DV2008. A timeout does not mean the operation did not run.
