Bug Description
most of the services are stateful, or depend on database.
it will cause issue when upgrade one of the services with others remain old.
for example if upgrade one nova-api to ocata, it can not read the DB schema successfully. and it can not send message through MQ, because the message struct is different.
On the other hand, if we upgrade the database and upgrade nova-api one by one, it will still cause the same issue.
serial is introduce for smooth upgrading. But apparently, it do not work as expected.
smooth upgrading should be handled by each roles rather than ansible serial feature.
