Step 8: Create pod instances

• The restful API request will be routed to V1Controller from RootController for the version is 'v1.0':

 tricircle/tricircle/api/controllers/root.py

class RootController(object):

   ....
   @expose()
   def _lookup(self, version, *remainder):
       if version == 'v1.0':
           return V1Controller(), remainder

• In V1Controller, because the request is to create pod, so the request will be forwarded to PodsController: https://github.com/openstack/tricircle/blob/master/tricircle/api/controllers/root.py#L76
• The pod creation will be handled in the post function: https://github.com/openstack/tricircle/blob/master/tricircle/api/controllers/pod.py#L44~#L116
