feat: add --to-disk option for provisioning compute node image to disk

Add new long option --to-disk to run-ci.sh that enables disk-based
provisioning of compute node images. When specified, the option sets
enable_todisk=1 in the vars file for use by downstream provisioning
scripts.

Changes:
- Add --to-disk long option to getopt parsing
- Add case handler for the new option
- Update help text with option description
- Export enable_todisk=1 to vars file when option is used
