feat: Add extraEnvs to operator-ui helm chart

[golgoth31]

This PR allows adding any needed extra anv vars to the operator-ui deployment into the helm chart.
Fixes #1523

Thanks. Lets add these commented lines directly to the deployment template and example manifest.

Is it what you intended ?

[FxKu]

Yes and the same for helm chart, too. This extraEnvs construct looks kinda strange to me.

[golgoth31]

I have added some comments in the values.yaml file the extraEnvs field

# configure extra UI ENVs
# Extra ENVs are writen in kubenertes format and added "as is" to the pod's env variables
# https://kubernetes.io/docs/tasks/inject-data-application/define-environment-variable-container/
# https://kubernetes.io/docs/reference/kubernetes-api/workload-resources/pod-v1/#environment-variables
# UI specific env variables can be found here: https://github.com/zalando/postgres-operator/blob/master/ui/operator_ui/main.py

does it seems ok ?
