Show environment in dashboard can be broken during deployment

[Margarita Shakhova]

Use case: the environment is deployed via Murano API request and if we do not use user-generated uuids for components in json data, i.e. part of json
"?":
{
"type" : "io.murano.resources.LinuxMuranoInstance"
}
missing "id" : <user generated uuid>

than environment view is broken during deployment:

(from horizon log):

  File "/usr/lib/python2.7/dist-packages/muranodashboard/environments/tabs.py", line 190, in get_context_data
    d3_data = api.load_environment_data(self.request, environment_id)
  File "/usr/lib/python2.7/dist-packages/muranodashboard/environments/api.py", line 373, in load_environment_data
    return topology.render_d3_data(request, environment)
  File "/usr/lib/python2.7/dist-packages/muranodashboard/environments/topology.py", line 288, in render_d3_data
   rec(service, None, service)
  File "/usr/lib/python2.7/dist-packages/muranodashboard/environments/topology.py", line 220, in rec
    rec(value, key, node_data)
  File "/usr/lib/python2.7/dist-packages/muranodashboard/environments/topology.py", line 203, in rec
    atomics.extend([('id', node_data['?']['id']),
KeyError: 'id'

The reason is that if id is not generated by user it is absent in session description and therefore unreachable for dashboard.
