neutron-server-start-wait-stop is a dangerous Exec that is exposed to race conditions, because it does not have "onlyif" or "unless" statements. That means during a deployment, this exec can be run in the wrong order during Step 5 and/or 6, while it was supposed to be run at Step 4 only. If that happens, the exec will fail because puppet tries to start neutron-server while Pacemaker already started the resource. So in that case, systemd would returns 1 to Puppet which would return 6 to the overcloud deployment and the deployment would fail to finish correctly. This patch aims to prevent from this scenario by making sure we run the exec only during the step 4. Also, in order to secure it a bit more, we add 'unless' statement to this exec, so we would make sure the Puppet run would be idempotent and the Exec would run one successful time only. https://bugzilla.redhat.com/show_bug.cgi?id=1290582 Change-Id: I42813c5cff6c525c15c9c24baad4e355f88af672

Directories
A description of the directory layout in TripleO Heat Templates.
- environments: contains heat environment files that can be used with -e
on the command like to enable features, etc.
- extraconfig: templates used to enable 'extra' functionality. Includes
functionality for distro specific registration and upgrades.
- firstboot: example first_boot scripts that can be used when initially
creating instances.
- network: heat templates to help create isolated networks and ports
- puppet: templates mostly driven by configuration with puppet. To use these
templates you can use the overcloud-resource-registry-puppet.yaml.
- validation-scripts: validation scripts useful to all deployment
configurations
