Flask and flower should use a ingress

In the merge request, !1 (merged) was changed

-   type: ClusterIP
+   type: LoadBalancer

We should revert this change and make sure that if we set (in values.yaml)

gwcelery.ingress.enabled=true
gwcelery.ingress.hosts=gwcelery.default.svc.cluster.local. #Ingess address

it works.
