[aws] `--allow-reboot` stop /start the instance

When perfroming a deploy operation withe the --allow-reboot flag nixops actually stop start the instance which can cause issues when dealing with spot instances. It should reboot the instance as the name suggest

nixops deploy -d dep --allow-reboot

In that case, I believe you should use the --force-reboot option
