After upgrading Cilium to 1.8 via kops one of our clusters had a total outage due to cilium reporting errors as below: ``` level=error msg="endpoint regeneration failed" containerID= datapathPolicyRevision=0 desiredPolicyRevision=1 endpointID=592 error="Failed to load tc filter: exit status 1" identity=40147 ipv4= ipv6= k8sPodName=/ subsys=endpoint ``` upon searching Cilium slack we found the below thread: https://cilium.slack.com/archives/C1MATJ5U5/p1616400216167600 which recommended setting `enable-host-reachable-services` to true will address the problems. We set the field and it fixed our issues too, however we observed that kops does not have a means to configure this hence this PR. We will like to have this backported after it has been merged.
This completes kubernetes#11333. I missed these updating these other template files when I submitted kubernetes#11333.
