Allow Resources to select paths from attributes

Previously when get_attr included a path to select from the attribute, the
selection was done by the get_attr intrinsic function. Starting with the
Juno version of HOT, move control of this to the resource plugin, so that
individual resources (particularly ResourceGroup) can handle it themselves.
