Mutating admission controller to fix jenkin's crap

Based on: https://github.com/morvencao/kube-mutating-webhook-tutorial

What it does

When it's deployed if a pod has this annotation:

cloudbees-pse-fixer.prezi.com/activate: "yes"

All volume mounts mounting /var/lib/jenkins will be removed from the pod. Why? Because we are installing stuff there and we only need /var/lib/jenkins/workspace to be a volume.

Deploying

No fancy integrations yet, the jist of it is this:

./scripts/build.sh  # build and upload image
./scripts/deploy.sh # deploy it

Certificates

The admission controller depend on some certificates to be availabe for the API to work. To regenerate that please use

./scripts/create-signed-cert.sh
