kubectl speedup with persistent proxies

Installation

Put the kubectl-speedup script somewhere on your PATH, eg.:

curl -O /usr/local/bin/kubectl-speedup https://github.com/reegnz/kubectl-speedup/master/kubectl-speedup

Then make sure you wrap it with a shell function, like so (in your .bashrc or .zshrc):

function kubectl() {
  kubectl-speedup "$@"
}

Initial benchmarks with hyperfine show a 1.6x speedup when working with an AWS-EKS cluster that's in West-coast US and is accessed from Europe.
