hey everyone, is there any way to set max unavailable on the dagster helm chart for the user deployment? I want to be sure that if some one pushes a build with an error it doesn't take down the previous version

Hi Jacob - just looking through the chart here: https://github.com/dagster-io/dagster/blob/master/helm/dagster/charts/dagster-user-deployments/templates/deployment-user.yaml#L3-L19 - I don't think we expose a value to control this in the chart currently, but it wouldn't be a big lift to add it
when we update the chart we sometimes use ``--atomic --cleanup-on-fail `` in the helm upgrade command which I believe makes it roll back if there's an error
