Flannel use interface for inter-host communication setted on --iface options
Defaults to the interface for the default route on the machine.
flannel config set via daemonset, and flannel config on all nodes is the same.
But different nodes can have different interface names for the inter-host communication network
The option --iface-regex allows the flannel to find the interface on which the address is set from the inter-host communication network
* Updates Controller Manager/Kubelet with Flannel's required configuration for CNI
* Removes old Flannel installation
* Install CNI enabled Flannel DaemonSet/ConfigMap/CNI bins and config (with portmap plugin) on host
* Uses RBAC if enabled
* Fixed an issue that could occur if br_netfilter is not a module and net.bridge.bridge-nf-call-iptables sysctl was not set
* Add restart for weave service unit
* Reuse docker_bin_dir everythere
* Limit systemd managed docker containers by CPU/RAM. Do not configure native
systemd limits due to the lack of consensus in the kernel community
requires out-of-tree kernel patches.

Each node can have 3 IPs.
1. ansible_default_ip4 - whatever ansible things is the first IPv4 address
usually with the default gw.
2. ip - An address to use on the local node to bind listeners and do local
communication. For example, Vagrant boxes have a first address that is the
NAT bridge and is common for all nodes. The second address/interface should
be used.
3. access_ip - An address to use for node-to-node access. This is assumed to
be used by other nodes to access the node and may not be actually assigned
on the node. For example, AWS public ip that is not assigned to node.
This updates the places addresses are used to use either ip or access_ip and walk
up the list to find an address.
