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

[Corey Bryant]

Public bug reported:

[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.

[Regression Potential]
Will evaluate more next week but the fix has already landed in the stable/stein branch upstream.
