What this PR does / why we need it:

• background:
  pool coordinator cert controller is used for preparing certificates for pool coordinator component, and it should wait for service of pool-coordinator ready before creating certificates. At present, all certificates preparation is handled in controller setup, so other controllers setup are blocked by pool coordinator cert controller.

• solution:
  separate allSelfSignedCerts into three kinds:

  • allIndependentCerts: don't depend on service, and can be prepared in controller setup phase.
  • certsDependOnAPIServerSvc: depend on apiserver service, and should be prepared in controller reconcile
  • certsDependOnETCDSvc: depend on etcd service, and should be prepared in controller reconcile
