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.
