Making the live-migration API friendly

Registered by Alex Xu

When performing live-migrate on an instance, admin should specify block_migration flag, it is really hard for admin and external system to use this API.

We can make those flags detected by nova automatically.
Host can specify with None, but would be great make it optional directly.
