Enable REST to manage devices under a proxy
This commit integrates the REST proxy within the standard REST
protocol and provider, supporting multiple devices managed by
a single REST end point (e.g. a REST-based second level controller).
It introduces the concept of RestSBServer, that represents
the REST service exposed by a single or a set of devices.
