CloudBees Replication Parent 2504

Previously, when scaling the High Availability (HA) multiple executor count up or down from the controller, agent processes on target operating systems (Linux or Windows) did not reflect the change dynamically. Additional executors remained in a disconnected state if the count was increased, and executor processes were not terminated when scaling down. This release introduces improvements to the agent runtime behavior. Now, when the executor count is increased or decreased from the controller, new Java agent processes are automatically spawned on target VMs during scale-up, and surplus agent processes are gracefully terminated during scale-down.
