c0d2cca45d 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.

d6f1f0c88b Make kubelet_load_modules always present but false. 
Update code and docs for that assumption.

Greg Althaus
8f00a07bf6 Due to the nsenter and other reworks, it appears that 
kubelet lost the ability to load kernel modules.  This
puts that back by adding the lib/modules mount to kubelet.

The new variable kubelet_load_modules can be set to true
to enable this item.  It is OFF by default.

- Since Weave 1.8.x was rewritten in Golang we may decrease RAM settings
  to continue using g1-small for CI

2d1109e09e 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.

94d9f03ddb 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.

3b816ee660 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.

7a9161d462 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.
