Gerry Kopec 5a7c6581ad Fix ssh config in nova to support cold migrations
- Fix .ssh/config file mapping
- Move private key from nova-compute-ssh container to nova-compute
  container.
- Map private and public keys to configmap-ssh which will default to
  the appropriate file permissions.
- Add additional config to /etc/ssh/sshd_config to allow passwordless
  root logins over appropriate subnet passed in from overrides.
- Remove chmods from sshd bash script as they are failing.

Depends on helm-toolkit supporting multiple containers per daemonset
pod.
