apply-routes.lua: Add a mechanism for per-device default volumes

Browse source 
This allows us to have per-device configuration for device volumes, via
a `device.routes.default-volume` property. This allows a non-global
override for situations where we want to expose a different out-of-box
volume (say for an internal speaker where we know a better comfortable
default setting, or HDMI where we might want to avoid attenuation by
default).
