kubectl multi-version brews

We need to run multiple versions of kubectl for compatibility with various kubernetes clusters.

It's a bit easier to get and use multiple versions of kubectl using Homebrew than it is using Macports.

With brew, it's simple to:

• Install a bunch of versions of kubectl (in the kubernetes-cli Formula)
• Switch between them as needed

# Copy secrets between two namespaces (from "default" to the "monitoring" namespace):
kubectl get secrets -o json --namespace default | jq '.items[].metadata.namespace = "monitoring"' | kubectl create -f  -

# Copy a specific secret (fx. a docker-registry secret used for pulling images from a private registry):
kubectl get secret dockercfg -o json --namespace default | jq '.metadata.namespace = "monitoring"' | kubectl create -f  -
