The nova-api, nova-scheduler nova-conductor packages are updated during
step2. The package upgrade trigger a restart of the service which fails
and is constantly retried by systemd:
Feb 24 12:34:24 centos-7-2-node-rax-iad-
7463943-440549 systemd[1]: Failed to start OpenStack Nova Scheduler Server.
Feb 24 12:34:24 centos-7-2-node-rax-iad-
7463943-440549 systemd[1]: Unit openstack-nova-scheduler.service entered failed state.
Feb 24 12:34:24 centos-7-2-node-rax-iad-
7463943-440549 systemd[1]: openstack-nova-scheduler.service failed.

7463943-440549 systemd[1]: openstack-nova-scheduler.service holdoff time over, scheduling restart.
We eventually reach timeout. We use
https://github.com/openstack/tripleo-heat-templates/blob/master/puppet/services/tripleo-packages.yaml#L44-L46
to upgrade existing packages.
Add a note to the README.rst to make people aware of the general upgrade
done at step3 and limit its usage to new package for individual service.

2) Stop all control-plane services, ready for upgrade
- 3) Perform a package update, (either specific packages or the whole system)
+ 3) Perform a package update and install new packages: A general
+ upgrade is done, and only new package should go into service
+ ansible tasks.
