As discussed during "[PATCH v4 00/29] vhost-user for input &
GPU"
review, let's define a common set of backend conventions to help with
management layer implementation, and interoperability.
v2:
- use a vhost-user.json schema to discover backends and describe
capability format
- drop --pidfile
- add some notes about daemonizing & stdin/out/err

Is it possible to actually use an external backend process with
all these yet ? If not, perhaps we should only start with the
backends that will be usable immediately ?
