Airgap install tasks

[npapapietro]

Having issues with airgap install, not sure if it is my lack of understanding but in the task below the agent and server are both installed https://github.com/k3s-io/k3s-ansible/blob/91ee70ee17d765df0dd42b0f92a7fbc75193bc63/roles/airgap/tasks/main.yml#L112

I don't think this is the case with the curl ... | sh - installer. Because of this I get random issues on restarting the node (use case) where the agent tries to consume the server args such as flag provided but not defined -write-kubeconfig-mode
