Delete nova.endpoint module, which used Tornado to serve up the Amazon EC2 API.

Replace it with nova.api.ec2 module, which serves up the same API via a WSGI app in Eventlet.
Convert relevant unit tests from Twisted to eventlet.

The unit tests now pass using eventlet 0.9.12 -- you'll need to 'pip install -U eventlet' or rebuild your venv.

Note that I tried to do this in discrete commits, so you may find it easier to look at each small diff than to try to grok the whole merge diff.
