To be able to run with the nobody user, an init container
is used in the haproxy-anchor pod to change the ownership and
permissions of '/host/etc/promenade/haproxy'. Security conext
was included in 'etc/kubernetes/manifests/haproxy.yaml' and
'promenade/schemas/Genesis.yaml' schema was updated to included
run_as_user property for haproxy pod.
