This update modifies the installation script to require a custom S3-compatible endpoint as a parameter. It ensures the endpoint is passed to both the script's environment and the Kubernetes secret used by Longhorn. This improves flexibility for setups using non-standard S3-compatible storage.
Introduce a bash script (`05_install_longhorn.sh`) to automate the installation of Longhorn using Helm, including S3 backup credentials setup. Include a new Helm values file (`longhorn.yaml`) to define default settings like replica count and S3 backup configuration.
