Zone migration strategy

Registered by Hidekazu Nakamura on 2017-04-05

There are thousands of physical servers and storage running various kinds of workloads in the Cloud system. Administrator have to migrate instances and block storage for hardware maintenance once a quarter or so.
It requires operators manually to watch workloads, choose instances to migrate and migrate for each instances and block storage for efficiently, with minimum downtime. Watcher can be used to do this task automatically.

The following items would be implemented:

- Add zone migration workflow engine which executes actions in parallel, in addition to manage volume quotas
- Add zone migration goal and strategy
