fix(controller): update Django admin fields

The declarative definition for presenting Build model objects
in the Django admin still referenced "sha," which is no longer
a field on the Build model. Same for the "version" field on
Config. Both of these caused a 500 error when browsing at
http://local.deisapp.com:8000/admin/

I also added "created" to Build, Config, and Release and
"domain" to Cluster in the admin list display.
fix(contrib/vagrant): fix vagrant n-node Makefile

The fleetctl commands weren't valid, and we should disable host
checking, as Vagrant nodes will change frequently.

faster and cheaper image downloads.

fix(logger): fix publish loop

before, the logger's publish loop would be searching for a TCP
connection. Since the logger runs on UDP, the publish loop would
not find it running and would run forever. This changes netstat
to search over UDP for the logger instead, allowing it to publish
its values to etcd.

fixes #738
feat(contrib/ec2): add m3 instances to template

The current generation of EC2 instances (M3) is faster and cheaper
than the old M1 instances. It's a more reasonable default to use
m3.medium as the default instance size.

refactor(seed-deis-registry): move to .service file

Moves seed-deis-registry to its own .service file, as it doesn't
need to run on all hosts (and shouldn't be specified in user-data).

docs(contrib): maintainers merge their own PRs

if the PR submitter is a maintainer, he or she merges it themself
(after 2 LGTMs). This is intended for commit stream cleanliness
and to allow them to fix their own PR before merging it.
fix(vagrant): use start on make run

the command hangs if there's nothing to restart, which is the case
when booting for the first time. It makes more sense for make run
to run make start, and the user should have to specify make
restart in order to restart a systemd unit.

fix(seed-deis-registry): move into deis-registry.service

Since we moved seed-deis-registry from the user-data file
in #770, the Makefile broke since we cannot perform many
systemctl actions on a oneshot service. This moves it into
an ExecStartPost after the deis-registry service starts.
