We should fix keystoneclient. KeystoneAuth is not doing anything wrong
here. I am against a "temp hack" like this. Secondarily, please submit
this patch to gerrit at review.openstack.org so that it can be
considered. Posting patches here is unlikely to be seen as
easily/readily.

Title:
  httpd leaks open files

Status in OpenStack Dashboard (Horizon):
  Confirmed
Status in keystoneauth:
  Won't Fix
Status in python-keystoneclient:
  Confirmed

Bug description:
  horizon version 13.0.0-1.el7 (Queens) on centos  7.4.1708

  After some time working on the dashboard, it stops working and throw
  this error in the error log

  [Wed Jul 04 22:49:33.744241 2018] [:error] [pid 23924] [remote
  10.144.187.237:52] IOError: [Errno 24] Too many open files:
  '/usr/share/openstack-
  dashboard/openstack_dashboard/templates/500.html'

  if we check the open files of this process 23924

   ls -l /proc/23924/fd | wc -l
  1023

  even if we increase the nofile limit of this process, it doesn't help as the open files is always increasing
  the problem is cleared if we restart the httpd process, but then the open files will increase again

  how to reproduce

  1- login to the dashboard
  2- get the pid from the error_log file
  [Wed Jul 04 22:50:58.620832 2018] [:error] [pid 23924] INFO openstack_auth.forms Login successful for user "demo" using domain "default"
  3- browse the dashboard different menus, specially the network topology tab
  4- monitor the open files no. with ls -l /proc/<pid>/fd | wc -l

  observation
  the no. is always increasing
