Sergii Golovatiuk c07d60bc90 Kubernetes Reliability Improvements
- Exclude kubelet CPU/RAM (kube-reserved) from cgroup. It decreases a
  chance of overcommitment
- Add a possibility to modify Kubelet node-status-update-frequency
- Add a posibility to configure node-monitor-grace-period,
  node-monitor-period, pod-eviction-timeout for Kubernetes controller
  manager
- Add Kubernetes Relaibility Documentation with recomendations for
  various scenarios.

Matthew Mosesohn 3c713a3f53 Fix upgrade for all daemonset type resources
Daemonsets cannot be simply upgraded through a single API call,
regardless of any kubectl documentation. The resource must be
purged and then recreated in order to make any changes.

Alexander Block 89e570493a Also add the system nameservers to upstream servers in dnsmasq
Also make no-resolv unconditional again. Otherwise, we may end up in
a resolver loop. The resolver loop was the cause for the piling up
parallel queries.

Aleksandr Didenko 54af533b31 Update playbooks to support new netchecker
Netchecker is rewritten in Go lang with some new args instead of
env variables. Also netchecker-server no longer requires kubectl
container. Updating playbooks accordingly.

Matthew Mosesohn f3a0f73588 Prevent dynamic port allocation in nodePort range
kube_apiserver_node_port_range should be accessible only
to kube-proxy and not be taken by a dynamic port allocation.

Potentially temporary if https://github.com/kubernetes/kubernetes/issues/40920
gets fixed.

'absible_ssh_host' is deprecated in Ansible 2.0 and at least
'contrib/inventory_builder/inventory.py' uses 'ansible_host' instead.

Artem Panchenko 1418fb394b 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.
