Feature: Ability to pass labels/annotations to job pods

[NetanelK]

Hi,
currently we're running Istio on our clusters with istio-proxy sidecar injector. We would like to disable istio-proxy on kube-fledged cache pods.

Istio provides a custom label sidecar.istio.io/inject="false" which needs to be present on pod's metadata.

We'll need a way to pass those custom labels to kube-fledged, annotations can be done the same way.
Another less preferred option is to deploy kube-fledged jobs into other namespace that imageCache resource namespace.

Hi,
Maybe we can simply add sidecar.istio.io/inject="false" in https://github.com/senthilrch/kube-fledged/blob/master/pkg/images/image_helpers.go#L52 ? I can create pr for this.
