features

[jbtrystram]

It would be great to have sa lib that does (at least) :

• Management api
• Command and control
• telemetry

That way if someone wants to implement a management tool (i.e. drg) or an "device" app (i.e. whatever on a raspberry pi) then use crates features to select needed api parts
drogue-client = {version: 0.2, features: ["management"]}

That way the crate can grow with mqtt and other stuff :)
