refactor: consolidate cloud-init userdata to shared/common.sh

Moved duplicate get_cloud_init_userdata() function from all 4 cloud
provider common.sh files to shared/common.sh. This eliminates 60+ lines
of duplication and centralizes cloud-init configuration.

Changes:
- Added get_cloud_init_userdata() to shared/common.sh with detailed comments
- Removed duplicate function from hetzner/lib/common.sh
- Removed duplicate function from digitalocean/lib/common.sh
- Removed duplicate function from vultr/lib/common.sh
- Removed duplicate function from linode/lib/common.sh
- Added comment that clouds can override if needed

All tests pass (42 passed, 0 failed).
