[WIP][DO NOT MERGE] l3afd in Kubernetes

[aojea]

This is a very basic installation manifest using my own repo just only for demo purposes, the project should host the docker images , I can help to set up this infra too

To try just do kubectl apply -f install.yaml and it will install the l3eafd daemon in all the nodes

kubectl -n kube-system get ds l3afd -o wide
NAME    DESIRED   CURRENT   READY   UP-TO-DATE   AVAILABLE   NODE SELECTOR   AGE     CONTAINERS   IMAGES               SELECTOR
l3afd   3         3         3       3            3           <none>          8m43s   l3afd        aojea/l3afd:v2.0.0   app=l3afd

The configuration is shared across the nodes via a configmap that is mounted in all the pods

 kubectl -n kube-system get cm l3afd
NAME    DATA   AGE
l3afd   1      9m29s
