Seems that this is an issue that only swift can solve. Hopefully this
gets done well before py2 is EOL so there can be a reasonable transition
period. IMO it would have to be at least a year, so swift should be
making it a critical effort to support Python 3 by the end of 2018. The
clock is ticking: https://pythonclock.org/

  This currently blocks neutron gate where we have a voting py3 tempest
  job. The reason why swift is deployed with Python3.5 there is because
  we special case in devstack to deploy the service with Python3:

  http://git.openstack.org/cgit/openstack-
  dev/devstack/tree/inc/python#n167

  The short term solution is to disable the special casing. Swift should
  then work on fixing the code, and gate on Python3 (preferably the same
  job as neutron has).
