Pre-version of 4a-hal-manager
Pre-version of 4a-hal manager that uses app-fwk DynAPI and app-controller. Current version : - Declare a new API for each HAL (each .json config file is used to generate one app-controller API) at startup. - Define verbs that will be provided by this API. - Provide verb to list and get info of loaded API. Change-Id: I7bb6e8b7539b1acd5556fd9275a1b536e129332d Signed-off-by: Jonathan Aillet <jonathan.aillet@iot.bzh>
