What this PR does / why we need it:
This Proposal takes over from the work in #6255 and focuses on

  • Define how labels propagate from ClusterClass to KCP/MachineDeployments/Machine Pools and down to Machines
  • Define how to prevent labels propagation triggers unnecessary rollouts

This proposal is complementary to #7296

Which issue(s) this PR fixes:
Fixes #493
