Instructions to deploy cbws / etcd-operator about etcd-operator

[nvtkaszpir]

Just use official helm chart from stable/etcd-operator and feed it with custom values file with modified images, such as:

etcdOperator:
  priorityClassName: ""
  name: etcd-operator
  replicaCount: 1
  image:
    repository: cbws/etcd-operator
    tag: v0.10.0
    pullPolicy: Always

Same for backup and restore operators.

Alo it is better to add CRD and then etcd CR as separate helm charts.

notice: we experience etcd cluster wipeout when using stable/etcd-operator helm chart (investigating why it wipes clusters....)
