This enables pacemaker maintenantce mode when running Puppet on stack update. Puppet can try to restart some overcloud services, which pacemaker tries to prevent, and this can result in a failed Puppet run. At the end of the puppet run, certain pacemaker resources are restarted in an additional SoftwareDeployment to make sure that any config changes have been fully applied. This is only done on stack updates (when UpdateIdentifier is set to something), because the assumption is that on stack create services already come up with the correct config. (Change I9556085424fa3008d7f596578b58e7c33a336f75 has been squashed into this one.)
