Implement the client-side device authentication ceremony.
Device authentication requires a previously registered and enrolled device. In
exchange for solving a challenge, the ceremony allows the user to augment their
certificates with device extensions, which are necessary to clear device-aware
authentication.
Wiring to `tsh` to be done in a follow-up PR.
