Fix StrongSwan handlers - handlers cannot be blocks

Ansible handlers cannot be blocks. Fixed by:

1. Making each handler a separate task that can notify the next handler
2. restart strongswan -> notifies -> wait for strongswan
3. rereadcrls -> notifies -> purgecrls

This maintains the proper execution order while conforming to Ansible's
handler constraints. The wait and retry logic is preserved.
