Add metallb load balancer as new service in the cluster

[rgroux]

Metallb is a load-balancer implementation for bare metal Kubernetes clusters, using standard routing protocols.

Kubernetes does not offer an implementation of network load-balancers (Services of type LoadBalancer) for bare metal clusters. The implementations of Network LB that Kubernetes does ship with are all glue code that calls out to various IaaS platforms (GCP, AWS, Azure…). If you’re not running on a supported IaaS platform (GCP, AWS, Azure…), LoadBalancers will remain in the “pending” state indefinitely when created.

in progress, testing.

actually fonctional. check for multiple deployement, and then find a good way to integrate into the pillar.

need to test other tools like traefik, and give the choice between metallb and traefik.
traefik add the ingress fonctionlily too and alsy some features about letsencrypt services
