Add converge parameter for stack update API and RPC call, that allow triggering observe on reality. This will be triggered by API call with converge argument (with True or False value) within. This flag also works for resources within nested stack. Implements bp get-reality-for-resources Change-Id: I151b575b714dcc9a5971a1573c126152ecd7ea93
