Add compile messages job config

[okaycj]

Job to run python manage.py compilemessages. Once we've confirmed this is working as intended, we'll need to remove the *.mo files from lookit-api.

I added @jtrouth as a reviewer as this is my first kustomization config. I basically copied the collectstatic config.

Closes #8

The job and kustomization files looks good. In order to have this deployed with lookit you'll also need to add - compilemessages to the resource list in kubernetes/lookit/base/kustomization.template.yaml

@jtrouth I have updated as you've stated above in commit 4a8fb93. Thank you, once again, for your help.
