VMware live migration

Registered by Radoslav Gerganov on 2016-03-25

This blueprint is for implementing live migration in the VMware driver.

When the VMware driver is used, nova-compute is managing a vCenter cluster.

For the purposes of this proposal we assume that all nova-computes are managing
clusters under the same vCenter server.

Live migration will be implemented using the VMware vMotion technology. In order
to migrate an instance, the source nova-compute needs to know the cluster name
and the datastore regex of the target nova-compute. The actual migration is a simple
matter of calling RelocateVM_Task() API.

We're past feature freeze for Rocky, so this must be deferred. Please re-propose the spec for Stein if you'd like to work on it next cycle. -- melwitt 20180727
