Deploy Flannel CNI definition into k8s

Description

This role contains a bunch of Flannel CNI definitions, and run kubectl apply -f <definition> to apply one them. It is suggested, that the user is able to use kubectl (f.e. because it has correct .kube/config file).

I collected some Flannel CNI definitions here, and will update when it's needed.

Role Variables

k8s_flannel_ver: version of flannel to deploy

k8s_flannel_network_pod_cidr: pod network cidr, default is 10.244.0.0/16

k8s_flannel_iface: network interface flannel will use for nodes inter-communication
