fix: Bump Cilium version and add required flags as required by latest GKE nodes

What does this MR do?

This is a fix for gitlab-org/gitlab#330131 (closed) which the most appropriate fix would be to update this repository to use Helm 3 and therefore allowing the use of the latest cilium charts.

However the Cilium chart 1.8.10 is still built for Helm 2 on the same time that it fixes the issues described in here. Some other attributes like nativeRoutingCIDR and ipam were required as part of the fix.

This has been manually tested in this project
