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. Signed-off-by: Bogdan Dobrelya <bogdando@mail.ru>

# Need to disable pipelining for bootstrap-os as some systems have requiretty in sudoers set, which makes pipelining
# fail. bootstrap-os fixes this on these systems, so in later plays it can be enabled.

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.

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
