[PATCH pve-guest-common v3 1/3] AbstractConfig: allow passing options to snapshot_rollback

[Jakob Klocker <j.klocker@proxmox.com>]

Thread an optional $opts hashref through snapshot_rollback to
__snapshot_rollback_vm_start, so callers can pass per-rollback options
down to the VM start. Used by qemu-server to let the API override the
guest time sync for a single rollback; other options can be added
without further signature changes.
