Enable the Machine Config Daemon (MCD) to apply non-disruptive MC changes (e.g., SSH keys, certificates) directly to live nodes, skipping OCL builds. detect live apply scenarios by checking if MC changes do not involve kernel/extensions/osimageurl changes. bypass the ocl image generation and ostree commit steps for the live-apply scenarios and preserve the disruptionless behavior for ssh key updates, cert rotations, and pull secret changes, etc.
