ambassador operator doesn't work when a proxy is needed

[sylvainOL]

Hello,
we're deploying k8s behind corporate proxy.

When we want to install Ambassador as Ingress controller using the operator, we have an issue as helm repository cannot be reached:

$ kubectl -n ambassador get AmbassadorInstallation -o yaml

apiVersion: v1
items:
- apiVersion: getambassador.io/v2
  kind: AmbassadorInstallation
  metadata:
    annotations:
      kubectl.kubernetes.io/last-applied-configuration: |
