cluster/tools/kartongips: init

This forks bitnami/kubecfg into kartongips. The rationale is that we
want to implement hscloud-specific functionality that wouldn't really be
upstreamable into kubecfg (like secret support, mulit-cluster support).

We forked off from github.com/q3k/kubecfg at commit b6817a94492c561ed61a44eeea2d92dcf2e6b8c0.
