5ed8f686b3 Explicitly set config path for DNSMasq
When DNSMasq is configured to read its settings
from a folder ('-7' or '--conf-dir' option) it only
checks that the directory exists and doesn't fail if
it's empty. It could lead to a situation when DNSMasq
is running and handles requests, but not properly
configured, so some of queries can't be resolved.

d30c52d53d Switch to ansible_hostname in calico
For consistancy with kubernetes services we should use the same
hostname for nodes, which is 'ansible_hostname'.

Also fixing missed 'kube-node' in templates, Calico is installed
on 'k8s-cluster' roles, not only 'kube-node'.

13ae324569 Fix calico-rr peering with k8s masters
Calico-rr is broken for deployments with separate k8s-master and
k8s-node roles. In order to fix it we should peer k8s-cluster
nodes with calico-rr, not just k8s-node. The same for peering
with routers.

Closes #925

eed32f9838 Allow to specify number of concurrent DNS queries
ndots creates overhead as every pod creates 5 concurrent connections
that are forwarded to sky dns. Under some circumstances dnsmasq may
prevent forwarding traffic with "Maximum number of concurrent DNS
queries reached" in the logs.

This patch allows to configure the number of concurrent forwarded DNS
queries "dns-forward-max" as well as "cache-size" leaving the default
values as they were before.

707e6a4642 This PR adds/or modifies a few tasks to allow for the playbook to
be run by limit on each node without regard for order.

The changes make sure that all of the directories needed to do
certificate management are on the master[0] or etcd[0] node regardless
of when the playbook gets run on each node.  This allows for separate
ansible playbook runs in parallel that don't have to be synchronized.

04fbe42aa6 If the inventory name of the host exceeds 63 characters,
the openssl tools will fail to create signing requests because
the CN is too long.  This is mainly a problem when FQDNs are used
in the inventory file.

THis will truncate the hostname for the CN field only at the
first dot.  This should handle the issue for most cases.

85efd263b3 When running on CentOS7 image in AWS with selinux on, the order of
the tasks fail because selinux prevents ip-forwarding setting.

Moving the tasks around addresses two issues.  Makes sure that
the correct python tools are in place before adjusting of selinux
and makes sure that ipforwarding is toggled after selinux adjustments.

bab6ec8477 Fix resolvconf
Do not repeat options and nameservers in the dhclient hooks.
Do not prepend nameservers for dhclient but supersede and fail back
to the upstream_dns_resolvers then default_resolver. Fixes order of
nameservers placement, which is cluster DNS ip goes always first.

0f0858703b Fix reverse umount in reset role
The Jinja2 filter 'reverse' returned an iterator instead of a list,
resulting in the umount task to fail.

Intead of using the reverse filter, we use 'tac' to reverse the output
of the previous task.

8679f10f71 Rework DNS stack to meet hostnet pods needs
* For Debian/RedHat OS families (with NetworkManager/dhclient/resolvconf
  optionally enabled) prepend /etc/resolv.conf with required nameservers,
  options, and supersede domain and search domains via the dhclient/resolvconf
  hooks.

* Drop (z)nodnsupdate dhclient hook and re-implement it to complement the
  resolvconf -u command, which is distro/cloud provider specific.
  Update docs as well.

* Enable network restart to apply and persist changes and simplify handlers
  to rely on network restart only. This fixes DNS resolve for hostnet K8s
  pods for Red Hat OS family. Skip network restart for canal/calico plugins,
  unless https://github.com/projectcalico/felix/issues/1185 fixed.

* Replace linefiles line plus with_items to block mode as it's faster.

aefe4a99d2 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.
