Explicitly set etcd authentication

[Spyros Trigazis]

Update etcd configuration:
Set authentication to true for both client and peer connections, set trusted_ca for both client and peer.

Without client and peer auth, etcd listens over ssl but it is not using the certs for authentication.

curl -k https://<IP>:2379/v2/keys/ was working and with the v3 api you can access the kubernetes objects.

Before running etcd in a container, the auth was set to true by etcd, the default change from the syscontainer:
