86e3506ae6 Etcd cluster setup makeover
The current way to setup the etc cluster is messy and buggy.

- It checks for cluster is healthy before the cluster is even created.
- The unit files are started on handlers, not in the task, so you mess with "flush handlers".
- The join_member.yml is not used.
- etcd events cluster is not configured for kubeadm
- remove duplicate runs between running the role on etcd nodes and k8s nodes

e5d8d8234d Remove proxy settings from etcd and kubernetes/master roles
When proxy vars are set, `uri` module tasks will attempt to route traffic through the proxy. This causes the "Wait for" tasks in the `etcd` and `kubernetes/master` roles to hang, as localhost connections struggle with a proxy.

As far as I know these roles only need local/cluster networking, so a proxy doesn't apply here anyway.

d94e3a81eb Use api lookup for kubelet hostname when using cloudprovider (#1686)
The value cannot be determined properly via local facts, so
checking k8s api is the most reliable way to look up what hostname

3a39904011 Move calico-policy-controller into separate role
By default Calico CNI does not create any network access policies
or profiles if 'policy' is enabled in CNI config. And without any
policies/profiles network access to/from PODs is blocked.

K8s related policies are created by calico-policy-controller in
such case. So we need to start it as soon as possible, before any
real workloads.

This patch also fixes kube-api port in calico-policy-controller
yaml template.

Closes #1132

ff8cb46bb9 Rework wildcards matching all nodes
* Re-enable ansible_ssh_pipelining as expected for the cluster.yml
* Do not use 'all' wildcasts for hosts, limit only to k8s-cluster, etcd,
  calico-rr groups instead. Other nodes in inventory are out of Kargo
  scope and it's up to users how to manage them.

a15d626771 Preconfigure DNS stack and docker early
In order to enable offline/intranet installation cases:
* Move DNS/resolvconf configuration to preinstall role. Remove
  skip_dnsmasq_k8s var as not needed anymore.

* Preconfigure DNS stack early, which may be the case when downloading
  artifacts from intranet repositories. Do not configure
  K8s DNS resolvers for hosts /etc/resolv.conf yet early (as they may be
  not existing).

* Reconfigure K8s DNS resolvers for hosts only after kubedns/dnsmasq
  was set up and before K8s apps to be created.

* Move docker install task to early stage as well and unbind it from the
  etcd role's specific install path. Fix external flannel dependency on
  docker role handlers. Also fix the docker restart handlers' steps
  ordering to match the expected sequence (the socket then the service).

* Add default resolver fact, which is
  the cloud provider specific and remove hardcoded GCE resolver.

* Reduce default ndots for hosts /etc/resolv.conf to 2. Multiple search
  domains combined with high ndots values lead to poor performance of
  DNS stack and make ansible workers to fail very often with the
  "Timeout (12s) waiting for privilege escalation prompt:" error.

* Update docs.

8168689caa Refactor roles and hosts
Shorten deployment time with:
- Remove redundand roles if duplicated by a dependency and vice versa
- When a member of k8s-cluster, always install docker as a dependency
  of the etcd role and drop the docker role from cluster.yaml.
- Drop etcd and node role dependencies from master role as they are
  covered by the node role in k8s-cluster group as well. Copy defaults
  for master from node role.
- Decouple master, node, secrets roles handlers and vars to be used w/o
  cross references.
