* Add method storageContext.Logger(). * Add method storageContext.System(). * Add method storageContext.CrlBuilder(). * Add method storageContext.GetUnifiedTransferStatus(). * Add method storageContext.GetPkiManagedView(). * Add method storageContext.GetCertificateCounter(). * Add method storageContext.UseLegacyBundleCaStorage(). * Add method storageContext.GetRevokeStorageLock(). * Add acmeState to acmeContext. Make acmeState accessible from acmeContext, so that storageContext doesn't have to be used for this purpose. * Decouple getAndValidateAcmeRole() from storageContext.Backend. * Don't access Backend.ciepsState through storageContext. * Add method storageContext.GetRole(). * Change signature of getCiepsAcmeSettings for CE compatibility.
