simple e2e test tool

[p0lyn0mial]

having a simple command line tool that would verify whether a node has been created serves not only as a good warm up exercise but also as a handy test tool.

the idea is that we would have a list of predefined machine manifests that would need some customisation in terms of credentials. The credentials could be accepted as a command line arguments and passed all the way down to the manifests. After POST'ing the given manifests to the kube-api server the test tool would read the current cluster state in order to determine the correctness of machine-controller

the test tool would use the standard client-go library to talk to the api server and would read the kubeconfig configuration file to discover where the cluster is actually located.

assumptions:

• cluster was created manually
• kube config is accessible
• there is a list of predefined machine manifests

for example, running the following command: verify -input path_to_manifest -parameters key=value, key2=value would print a machine "node-docker" has been crated to stdout.
