Problem:
Before, to customize CoreDNS, one had to edit the default configmap,
which gets re-written on every K3s server restart.
Solution:
Mount an additional coredns-custom configmap into the CoreDNS container
and import overrides and additional server blocks from the included
files.

K3s upgrade via watch over file change of static file and manifest
and triggers helm-controller for change. It seems reasonable to
only allow upgrade traefik v1->v2 when there is no existing custom
traefik HelmChartConfig in the cluster to avoid any
incompatibility.
Here also separate the CRDs and put them into a different chart
to support CRD upgrade.

Solution: Set priorityClassName to system-node-critical of traefik, metrics-server, local storage and coredns deployment

As per documentation, the cloud-provider flag should not be passed to
controller-manager when using cloud-controller. However, the legacy
cloud-related controllers still need to be explicitly disabled to
prevent errors from being logged.
Fixing this also prevents controller-manager from creating the
cloud-controller-manager service account that needed extra RBAC.

Resolves warning 2 from #2471.
As per https://github.com/kubernetes/cloud-provider/issues/12 the
ClusterID requirement was never really followed through on, so the
flag is probably going to be removed in the future.
One side-effect of this is that the core k8s cloud-controller-manager
also wants to watch nodes, and needs RBAC to do so.

Related to #1908
Will be fixed upstream by
https://github.com/rancher/local-path-provisioner/pull/135/ but we're
not going to update the LPP image right now since it's undergoing some
changes that we don't want to pick up at the moment.

Configure Traefik to update the Ingress Resources `loadBalancer` status.
This would provide users with at least following benefits:
1. It drastically simplifies the way one can quickly determine the relevant IP for a certain Ingress Resource, without the person deploying that Ingress needing to know how or where the LoadBalancer comes from.
2. Let's assume a User that has only permission to work in one specific namespace and is not allowed to *list* or *read* services from the `kube-system` namespace, for such a User this change would basically empower them to access the relevant information without being bottlenecked by another.
3. Allow tools like [external-dns](https://github.com/kubernetes-incubator/external-dns) to dynamically register all the available Ingress Resources with one of the Supported DNS Providers such as a local [CoreDNS](https://coredns.io).
Allow the kubelet resolv-conf flag to be set, or automatically
discovered from /etc/resolv.conf & /run/systemd/resolve/resolv.conf if
no loopback devices are present, or create our own which points to
nameserver 8.8.8.8
