CloudBees Replication Parent 2189

Previously, if the Pipeline: Job plugin (workflow-job) was not installed, class loading errors for PipelineDurabilityAdministrativeMonitor and other extensions appeared on CloudBees CI on traditional platforms controllers after installing the CloudBees High Availability (HA) (Active/Active) (cloudbees-replication) plugin. Now, the Pipeline: Job plugin (workflow-job) plugin is a required dependency for the CloudBees High Availability (HA) (Active/Active) (cloudbees-replication) plugin and is installed at the same time.
