Openvswitch user doesn't exist when updating ovs package to 2.8 onward during minor/major upgrade

[zenghui.shi]

Ovs uses openvswitch user when updating to 2.8 onwards,
but openvswitch user is not exist and will not be created
during ovs package update.

Ideally the problem shall be solved in ovs package itself,
for example, to add a section of preinstall scriptlet which
creates openvswitch user, this has been done for fresh
installation of ovs package, but not for package update yet.

In order to solve above problem, this is asking for adding
workarounds in tripleo to make sure openvswitch user exist
before running package update.

More detailed discussion can be found at:
https://bugzilla.redhat.com/show_bug.cgi?id=1559374

This issue exists for minor update, major upgrade and
fast-forward upgrade across all releases. Due to different
workflows of upgrade, the workaround may need to be added
in each of the workflows.

Change abandoned by zenghui.shi (<email address hidden>) on branch: master
Review: https://review.openstack.org/557155
Reason: Abandoning this patch as master doesn't need this change (fresh installation of ovs in master will have the right permission set, no need to patch it separately).

    Change ovs user and fix permissions on ovs upgrade

    When upgrading to latest ovs, package needs to run with
    ovs user, and also the affected folders need to change their perms.
    Change the config file for it, and initially do a perm change. Also
    create a one-time service file that will run after reboot, to be
    sure that all the remaining folders have changed their perms
    properly.
