Open port 80 on summit.o.o and add ttx.

* manifests/site.pp: Change the summit node to be an instance of the
new summit class rather than the more generic server class.

* modules/openstack_project/manifests/summit.pp: Add a new summit
class based on server, but open 80/tcp and realize an account for
ttx. Also explicitly list 22/tcp even though it's already included
by the server class.

* modules/openstack_project/manifests/users.pp: Add an entry for ttx
with his name and SSH public key.
