Install a RKE workload cluster with Cilium CNI to evaluate egress capability of Cilium open source

Some CNF need to communicate with other components (appliances, VNF...) that expect the traffic to always some with the same IP.

Besides better performance with eBPF, Cilium brings an Egress gateway feature that could potentially match with the requirement coming from those CNF: https://docs.cilium.io/en/stable/network/egress-gateway/

We need to deep dive into it, to better understand the feature and the impact of it on the Sylva design. Furthermore, we need to see if egress gateway solution is redundant in the open source solution, according to the documentation is it not: image
