Bug description:
  Description
  ===========
  Having upgraded three OpenStack deployments to Victoria, we have noticed that snapshots are now failing to be created. When a user attempts this via Horizon they receive an error such as:

  Error: Unable to create snapshot. Details

  Unexpected API Error. Please report this at
  http://bugs.launchpad.net/nova/ and attach the Nova API log if
  possible. <class 'AttributeError'> (HTTP 500) (Request-ID:
  req-7e4b0824-9884-4d50-b8ee-5184e245a11d)

  It appears that this can be worked around by adding 'from eventlet
  import tpool' and adjusting the 'eventlet.tpool.execute' call to match
  in nova/utils.py

  Steps to reproduce
  ==================
  Via Horizon on a Victoria deployment:
  - Create an instance
  - Suspend the instance
  - Create a snapshot

  Expected result
  ===============
  A snapshot should have been created

  Actual result
  =============
  Error message as above

  Environment
  ===========
  1. Exact version of OpenStack you are running.

  Git hash cb4963ba8c4babb7e460d71daf91099fc6da1dc6

  2. Which hypervisor did you use?

  Libvirt+KVM

  2. Which storage type did you use?

  Ceph Octopus

  3. Which networking type did you use?

  Neutron with Linux Bridge

  Logs & Configs

  The full traceback from the API is as follows:
