Device property.

Each string in the list is a JSON serialised dict defining the group_name, devices and subgroups in the group. A Tango Group object is created for each item in the list, according to the hierarchy defined. This provides easy access to the managed devices in bulk, or individually.

The general format of the list is as follows, with optional devices and subgroups keys:

[ {"group_name": "<name>",
   "devices": ["<dev name>", ...]},
  {"group_name": "<name>",
   "devices": ["<dev name>", "<dev name>", ...],
   "subgroups" : [{<nested group>},
                    {<nested group>}, ...]},
  ...
  ]

For example, a hierarchy of racks, servers and switches:

[ {"group_name": "servers",
   "devices": ["elt/server/1", "elt/server/2",
                 "elt/server/3", "elt/server/4"]},
  {"group_name": "switches",
   "devices": ["elt/switch/A", "elt/switch/B"]},
  {"group_name": "pdus",
   "devices": ["elt/pdu/rackA", "elt/pdu/rackB"]},
  {"group_name": "racks",
   "subgroups": [
        {"group_name": "rackA",
         "devices": ["elt/server/1", "elt/server/2",
                       "elt/switch/A", "elt/pdu/rackA"]},
        {"group_name": "rackB",
         "devices": ["elt/server/3", "elt/server/4",
                       "elt/switch/B", "elt/pdu/rackB"],
