Bindings V2: Remove explicit references to daemon/service
Usage shown that managing daemon interface and service interface wasn't obvious. This evolution hides the complexity by setting up an internal hidden variable. Change-Id: I667b1ee4e3a7b5ad29d712ee20ad5dd1878b97f3 Signed-off-by: José Bollo <jose.bollo@iot.bzh>
