Subject: [PATCH] refactor: consolidate SSH_OPTS to shared/common.sh

Moved duplicate SSH_OPTS constant from all 4 cloud provider common.sh
files to shared/common.sh. This removes 4 lines of duplication and
centralizes SSH configuration.

Changes:
- Added SSH_OPTS to shared/common.sh with comment explaining clouds can override
- Removed SSH_OPTS from hetzner/lib/common.sh
- Removed SSH_OPTS from digitalocean/lib/common.sh
- Removed SSH_OPTS from vultr/lib/common.sh
- Removed SSH_OPTS from linode/lib/common.sh

All tests pass (42 passed, 0 failed).
