to re-encrypt data automatically by the service through a CustomerProvidedEncryptionKey.
Added support for the keyword user_delegation_tid to BlobServiceClient.get_user_delegation_key API, which
can be used in generate_blob_sas and generate_container_sas to specify the Tenant ID that is authorized
to use the generated SAS URL. Note that user_delegation_tid must be used together with user_delegation_oid.
Added support for the keyword request_headers to generate_blob_sas and generate_container_sas,
which specifies a set of headers and their corresponding values that must be
present in the request header when using the generated SAS.
