A helper tool for getting and editing Kubernetes data directly from Etcd,
# Abstract
This is a modified version of [etcdhelper](https://github.com/openshift/origin/tree/master/tools/etcdhelper) from OpenShift and subsequent modifications made by [Flant](https://flant.com/).
We added: `change-provider-id` allowing you to edit the `node.spec.providerID` of any existing Kubernetes node.
