As of version 1.1.2 of Nomad, the CLI monitors job deployments by
default until they are finished. Thus our custom job deployment
watcher script is not required anymore.
Previously we used this file to deploy a job on Nomad that our API
used for e2e tests. Now that we create the environments in the e2e
tests, we don't need the demo job anymore.
We previously didn't really had any structure in our project apart
from creating a new folder for each package in our project root.
Now that we have accumulated some packages, we use the well-known
Golang project layout in order to clearly communicate our intent
with packages. See https://github.com/golang-standards/project-layout
