Kubernetes job to cron-ishly run a Travis CI sync.
sqre-travissync requires the environment variable GITHUB_TOKEN to be
set. That token must be exchangeable for a Travis CI token, and the
user associated with that token will be the one who runs the sync.
Do this by copying traviscisync-secrets.yaml to a temp file, updating
the secret, and running kubectl create -f secret-file on it. Then run
kubectl create -f kubernetes\traviscisync-job.yaml to create the job.
...or at least this would work if GKE supported CronJobs.
As it is, install the package sqre-travissync, and then run
sqre-travissync once GITHUB_TOKEN is set.
