Provide unit in config.xml and documentation

This commit remove urn:AGL:widget:provided-application in favour of urn:AGL:widget:provided-unit. In the same time, the feature urn:AGL:widget:provided-api must be attached to a unit. This will enable to export more than one API for a unit if needed. Change-Id: I17ade3651db2cd61402875333d063ee05cf57a10 Signed-off-by: José Bollo <jose.bollo@iot.bzh>
