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.

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.
