CLOUDSTACK-7559 After migrating root volume to other cluster wide storage, start VM is not running the VM with root disk from new storage.

Changes:
- During VM start, do not use the last host Id, if the host's cluster does not match the cluster provided in the deployment plan.
CLOUDSTACK-5853 cannot deploy vm with differing service storage tag and data disk storage tag

Changes:
- Reverting Marcus's fix since this issue has already fixed by https://issues.apache.org/jira/browse/CLOUDSTACK-5426
