* Add dns_replicas, dns_memory/cpu_limit/requests vars for dns related apps. * When kube_log_level=4, log dnsmasq queries as well. * Add log level control for skydns (part of kubedns app). * Add limits/requests vars for dnsmasq (part of kubedns app) and dnsmasq daemon set. * Drop string defaults for kube_log_level as it is int and is defined in the global vars as well. * Add docs Signed-off-by: Bogdan Dobrelya <bdobrelia@mirantis.com>
