Tune dnsmasq/kubedns limits, replicas, logging * 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>

# Limits for dnsmasq/kubedns apps
dns_memory_limit: 170Mi
Make kubedns up to date Update kube-dns version to 1.14.2 https://github.com/kubernetes/kubernetes/pull/45684

kubedns_min_replicas: 2
Add autoscalers for dnsmasq and kubedns By default kubedns and dnsmasq scale when installed. Dnsmasq is no longer a daemonset. It is now a deployment. Kubedns is no longer a replicationcluster. It is now a deployment. Minimum replicas is two (to enable rolling updates). Reduced memory erquirements for dnsmasq and kubedns

Add CoreDNS support with various fixes Added CoreDNS to downloads Updated with labels. Should now work without RBAC too Fix DNS settings on hosts Rename CoreDNS service from kube-dns to coredns Add rotate based on http://edgeofsanity.net/rant/2017/12/20/systemd-resolved-is-broken.html Updated docs with CoreDNS info Added labels and fixed minor settings from official yaml file: https://github.com/kubernetes/kubernetes/blob/release-1.9/cluster/addons/dns/coredns.yaml.sed Added a secondary deployment and secondary service ip. This is to mitigate dns timeouts and create high resitency for failures. See discussion at 'https://github.com/coreos/coreos-kubernetes/issues/641#issuecomment-281174806' Set dns list correct. Thanks to @whereismyjetpack Only download KubeDNS or CoreDNS if selected Move dns cleanup to its own file and import tasks based on dns mode Fix install of KubeDNS when dnsmask_kubedns mode is selected Add new dns option coredns_dual for dual stack deployment. Added variable to configure replicas deployed. Updated docs for dual stack deployment. Removed rotate option in resolv.conf. Run DNS manifests for CoreDNS and KubeDNS Set skydns servers on dual stack deployment Use only one template for CoreDNS dual deployment Set correct cluster ip for the dns server

Add advanced net check for DNS K8s app * Add an option to deploy K8s app to test e2e network connectivity and cluster DNS resolve via Kubedns for nethost/simple pods (defaults to false). * Parametrize existing k8s apps templates with kube_namespace and kube_config_dir instead of hardcode. * For CoreOS, ensure nameservers from inventory to be put in the first place to allow hostnet pods connectivity via short names or FQDN and hostnet agents to pass as well, if netchecker deployed.
