[Greenhouse] Steps for moving the deployment off dotcloud

[Asheesh Laroia]

Steps Dave can do:

* Make sure you have a WSGI "application" that will run the Django app

(this sounds harder than it is. Django usually autogenerates a wsgi.py 
that you can use for the purpose.)

* Make sure that you can use gunicorn to serve the app, on a port of your 
choosing, on vm3.openhatch.org

Steps Asheesh can do:

* Once the above is ready, Asheesh can switch things up so that mod_wsgi 
does the work that gunicorn used to do.
