    Use systemd-tmpfiles to create /var/run/uwsgi
    
    On ubuntu contents of /var/run do not persist between reboots. Devstack
    uses /var/run/uwsgi as home for wsgi sockets. This means that after
    rebooting the machine services, that rely on uwsgi would fail to start.
    Currently it affects keystone.service and placement-api.service.
    This patch changes delegates directory creation to systemd-tmpfiles,
    which would run on startup.

Title:
  [devstack] keystone service fails to start after reboot

Status in devstack:
  Fix Released
Status in OpenStack Identity (keystone):
  Invalid

Bug description:
  Enviroment
  OS: CentOS7.2

  I deployed the devstack environment successfully in CentOS system.
  After rebooting the CentOS system， the keystone service could not be
  started. The uwsgi raised exception as follows.

  Apr 23 22:38:53 devstack.localdomain systemd[1]: devstack@keystone.service failed.
  Apr 23 22:42:46 devstack.localdomain systemd[1]: Starting Devstack devstack@keystone.service...

  Apr 23 22:42:46 devstack.localdomain systemd[1]: Failed to start Devstack devstack@keystone.service.

  Apr 23 22:42:46 devstack.localdomain systemd[1]: devstack@keystone.service failed.

  So i think this is a bug. I tried to create the /var/run/uwsgi directory and chown it stack user. Then it works.
  sudo mkdir -p /var/run/uwsgi
  sudo chown stack:stack uwsgi

  So what do you think that?
