Fix issue 853
Fix the AAD single-tenant login issue.
Fix issues:
1.update keyvault SDK to 4.1.0. 2.refine keyvault specific keys handle logic.
PS: Because of the new keyvault SDK use SDK: azure-identity to do authentication, so the old credential related classes have been deprecated such as com.microsoft.azure.keyvault.spring.AzureKeyVaultCredential and com.microsoft.azure.keyvault.spring.KeyVaultCertificateCredential.
