Watching stops working after 10 minutes

Watching a set of configmaps fails to be alerted of new changes after 10 minutes of no changes.

##Repro steps

1. Install the following configmap into a cluster

apiVersion: v1
kind: ConfigMap
metadata:
  name: grafana-test-dashboard
  labels:
    grafana_dashboard: "1"
data:
  cm-test.json: {}

1. Install the sidecar into the cluster

apiVersion: v1
kind: Pod
metadata:
  name: test
spec:
  containers:
    - env:
        - name: METHOD
        - name: LABEL
          value: grafana_dashboard
        - name: FOLDER
          value: /tmp/dashboards
        - name: RESOURCE
          value: both
      image: kiwigrid/k8s-sidecar:0.1.178
      imagePullPolicy: IfNotPresent
      name: grafana-sc-dashboard

1. Wait 10 minutes
2. Make a change to the config map and update in the cluster

Expected Behaviour

Will see a modification occur

Actual Behaviour

Nothing

Cross posting from kubernetes/kube-state-metrics#694:

I started to think this issue to be mainly happening on to hosted Kubernetes services like AKS and EKS. There are many here using it without any issue, and there is another set of users who are repeatedly experiencing issues.

Also see this weird issue stops suddenly stopping for some set of users in a python implementation. kiwigrid/k8s-sidecar#85

Maybe the issue is lying in the way how the apiserver is hosted behind a managed load balancer.

Actually lets do do the same quick poll here among AKS/EKS users, can you vote this entry with:

• upvote (+1 ) if you are experiencing issue on AKS/EKS
• downvote (-1 ) if you are not experincing this issue on AKS/EKS
