Description of changes:
 This PR implements certificate renewal functionality for Ubuntu and RHEL nodes in EKS Anywhere clusters. This is part 2 of the certificate renewal feature, focusing on Linux-based operating systems. Key features include:
- Direct certificate management for Ubuntu and RHEL nodes
- SSH-based secure certificate deployment system
- Automatic certificate backup and validation
- Support for control plane certificate renewal
- Secure handling of SSH keys with optional passphrase protection
- Automatic kubeconfig discovery based on cluster name from input YAML file
- Extract new kubeconfig when local kubeconfig has expired
- Configurable logging verbosity with
-vflag to control output detail level- Default mode shows only essential information
- Verbose mode (
-v=2) displays detailed renewal process information
This PR builds on the configuration structure from part 1, implementing the renewal logic for traditional Linux distributions.

Hi @howard-junec. Thanks for your PR.
I'm waiting for a aws member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.
Once the patch is verified, the new status will be reflected by the ok-to-test label.
I understand the commands that are listed here.
