Split in two: agl-identity-service and uds-ble-id-init-service

The binding is splitted in two parts and packeged as widgets.
The two parts are:

 - uds-ble-id-init-service

    This service provides a UDS (User Data Service) over
    BLE. It detects writes to the email of the user to
    initiate the authentication process.

 - agl-identity-service

    This service queries the Forgerock's Edge Controller
    to fill user data and make it available.

The actual code is not fully functionnal.
