write authentication backend for "agent-style" sshd authentication
https://bugzilla.mindrot.org/show_bug.cgi?id=1663 is looking likely for inclusion in OpenSSH as a way to reduce the demands for explicit LDAP integration.
We need to review it, and write a monkeysphere backend for it. It is entirely possible that this agent approach doesn't work for our purposes (or is somehow suboptimal) so now is the right time to encourage any API shifts we find we need.
