Title:
  Nova kilo requires concurrency 1.8.2 or better

Bug description:
  OpenStack Nova Kilo release requires 1.8.2 or higher, this is due to
  the addition of on_execute and on_completion to the execute(..)
  function.  The latest Ubuntu OpenStack Kilo packages currently have
  code that depend on this new updated release.  This results in a crash
  in some operations like resizes or migrations.

  https://github.com/openstack/requirements/commit/2fd00d00db5fce57d9589643801942d0332b1670

  This commit above shows that OpenStack now requires 1.8.2 instead of
  1.8.0.  We would appreciate if the 1.8.2 upstream release can be
  brought in to resolve this bug.

  Thank you.
