The current migration protocol has several flaws
- No initial hook on the source host to do work before
the dst VM is launched
- No ability to restart src VM if dst fails to recv all
migration data, but src successfully sent it all
This introduces a new 5 step migration process to address
this limitation. To support features such as seemless
migration of SPICE clients, and lock driver state passing
this now makes use of the migration cookie feature too
