  - Merge "Changing Pull Policy for vFw Helm chart"
  - Changing Pull Policy for vFw Helm chart

    Pull policy is "Always" because of that
    VM/container images are pulled everytime
    for each chart. This slows down the
    deployment to several minutes in the
    lab environment. Changing pull policy to
    "IfNotPresent".
