tl;dr - No objections to reworking the swap volume API in Train

https://etherpad.openstack.org/p/ptg-train-xproj-nova-cinder - L3-18


- Deprecate the existing swap volume API in Train, remove in U.

- Deprecate or straight up remove existing CLI support for the API.

- Write up a spec introducing a new API specifically for use by Cinder
  when retyping or migrating volumes. Potentially using the external
  events API or policy to lock down access to the API.

- Optionally rework the Libvirt virt driver implementation of the API to
  improve performance and better handle failure cases as suggested by
  mdbooth. This might include introducing and using a quiesce volume

I'm personally out for the next two weeks but will start on the above
items once back.
