Split between packer / ansible and CodeDeploy phases for spin.py needs work

[obscurerichard]

I noticed that running packer and ansible left these files around (in the :

	emperor.ini
	src/infra-demo.ini

It looks like the split between the Ansible portion of the Python app deploy and the CodeDeploy portion is not quite right now. If we're going to use the WSGI Emperor, we should make sure it is installed in the base image, and then have the complete app, including the app-level WSGI file, get installed by the CodeDeploy package. Right now both configs are installed by Ansible / Packer.
