Helm install operator using released versions for released images

[alex-hunt-materialize]

Helm install operator using released versions for released images. Also fix waiting for crd to be established.

Motivation

Fixes mix/match of orchestratord and helm chart. Previously we always used the current in-git helm chart, even for much older releases of orchestratord. The helm chart is not backwards compatible with older orchestratord versions, so that breaks, for example, when adding new args to orchestratord.
