When deploying 3scale via the operator, the `ImagePullPolicy` is not configured consistently across `Containers` and `InitContainers`. It appears that we hard code this value as `PullIfNotPresent` in the Containers but we do not specify it for the `InitContainers` so it defaults to `Always`.

This can be problematic when deploying in a disconnected environment.

In addition, Production environments have some benefit from using `PullIfNotPresent`. If the registry is down, the `Always` in the `InitContainers` can cause the pod to fail to come up.

Ideally, these would be both be consistent and configurable from the APImanager/APIcast CRDs.
