Allow ResourceGroup to select an attribute path

Starting with the Juno version of HOT, ResourceGroup will take the path
into account when returning a list of attributes from get_attr. So
something like:

  {get_attr: [my_rsrc_group, networks, <network_name>, 0]}

will return a list of the first IP address of each server in the resource
group.
