Code cleanup for Heat Resource Topology

[Lin Hua Cheng]

The code for ajax query should be moved from stacks/api.py (https://review.openstack.org/#/c/36351/7/openstack_dashboard/dashboards/project/stacks/api.py) into the stacks/views.py.

The api class should only code for abstracting the backend call and is not intended for returning ajax response. Please move the code to views.py

    Fixing the AJAX function location

    This bug addresses the incorrect location of the AJAX function call in api.py and moves it to the correct location in views.py
    It also standardizes the AJAX JSON function to use a generic Django class instead of a function.
