Remove scripts and templates which dealt with Pacemaker and its
resource restarts before we moved to containerized deployments. These
should all now be unused.
Many environments had this mapping:
OS::TripleO::Tasks::ControllerPreConfig: OS::Heat::None
OS::TripleO::Tasks::ControllerPostConfig: OS::Heat::None
OS::TripleO::Tasks::ControllerPostPuppetRestart: ../../extraconfig/tasks/post_puppet_pacemaker_restart.yaml
The ControllerPostPuppetRestart is only ever referenced from
ControllerPostConfig, so if ControllerPostConfig is OS::Heat::None, it
doesn't matter what ControllerPostPuppetRestart is mapped to.
