Special Notes for Your Reviewer

I want to enable the serviceMonitor option when installing Cilium CNI as custom_cni. However, I couldn't find a way to deploy the ServiceMonitor CRD prior to CNI installation. So I want to add a feature to deploy the prerequisite resources that should be deployed before the CNI during the custom_cni deployment process.

Additionally, I have prepared a new PR to enable pre-deployment of Ansible Roles if the pre-deployment feature for resources is merged in any form (custom_cni, generic, ...). This was necessary because while deploying Cilium CNI, I encountered an issue where the deployment of hubble-relay failed due to CoreDNS not being active when the peer service was enabled on cilium-agent. This PR aims to address that problem.

Does this PR Introduce a User-Facing Change?

No, this new method is managed by new variable custom_cni_preflight_templates.
