[Bug 1866361] Re: [SRU] Connections to Neutron are not closed properly in v0.26.0

[Corey Bryant]

** Description changed:

  [Impact]
  <LarsErikP> Lars Erik Pedersen in #ubuntu-server reports the following issue:
  
  The problem we're having is with octavia-dashboard. If you leave a
  browser at the load-balancer page, apache starts to accumulate threads,
  and will eventually run out of memory. I recently tested by installin
  openstack 0.27.0 with pip, and that fixed the issue
  
  He has tested with 0.27.0 installed from pip and it fixes the issue for
  him.
  
  The related fix we believe is
  https://github.com/openstack/openstacksdk/commit/41740827c4702e8fcaebdf6adf7a2d49a557ec14
  
  They do seem to be related, though s/pids/threads.
  
  For more details on the original bug see:
  https://storyboard.openstack.org/#!/story/2005306
  
  [Test Case]
  Deploy openstack stein with octavia + octavia-dashboard. Leave a browser at the load-balancer page, apache starts to accumulate threads, and will eventually run out of memory. Lars has volunteered to test this once it is in proposed.
  
  Additional deployment/tempest regression testing will also be required
  by the openstack team.
  
  [Regression Potential]
  This fix has already landed in the stable/stein branch upstream, helping to mitigate regression potential.
  
  The version bump for stable/stein has been reviewed at:
  https://review.opendev.org/#/c/649154/
  
  The change does make an API change, as can be seen here (note the differences between Proxy and OpenStackSDKAdapter):
  https://docs.openstack.org/openstacksdk/rocky/contributor/layout.html#proxy
  https://docs.openstack.org/openstacksdk/stein/contributor/layout.html#proxy
  
  The change requires a minimum of keystoneauth1==3.13.0, and we already
  have 3.13.1 in the stein cloud archive.
+ 
+ [Discussion]
+ Plan is to bump python-openstacksdk from 0.26.0 to 0.27.0 for stein inline with upstream. This is not the typical process we follow, but in this case there is an API change and the only patch in the new minor release that affects package behavior is the the patch for this fix (the 3 other patches are to .zuul.yaml, .gitreview, and tox.ini).
