HE 環境が Maintenance Mode の場合でも、"Global Maintenance" のチェック中に engine-setup が失敗する理由

Issue

• RHV-Manager で # engine-setup を実行中に、以下のエラーがログに記録されます。

[ ERROR ] It seems that you are running your engine inside of the hosted-engine VM and are not in "Global Maintenance" mode. In that case you should put the system into the "Global Maintenance" mode before running engine-setup, or the hosted-engine HA agent might kill the machine, which might corrupt your data

• hosts-engine --vm-status は、グローバルメンテナンスモードの HE 環境を示します。
