Title:
  wait_until_true is not rootwrap daemon friendly

Status in neutron:
  Invalid

Bug description:
  As wait_until_true uses an eventlet timeout, it can happen that
  timeout exception is raised while waiting for output from rootwrap
  daemon. This leaves data in rwd socket and next attempt to run command
  via rootwrap daemon returns the previous data. There is a bug reported
  on oslo.rootwrap - https://bugs.launchpad.net/neutron/+bug/1654287

  With a switch of fullstack tests to use rootwrap, it happens a lot
  that timeouts are raised while running commands in rwd (eg.
  http://logs.openstack.org/67/488567/2/check/gate-neutron-dsvm-
  fullstack-ubuntu-xenial/eb8f9a3/testr_results.html.gz)

  This bug is to track down an eventlet free solution - we can
  generalize approach here
  https://review.openstack.org/#/c/421325/3/neutron/cmd/netns_cleanup.py
  and since we'll get rid of eventlet dependency, we can move
  wait_until_true to neutron-lib.
