This function writes the certificate and key to temporary files so that ssl.create_default_context can load them, as the ssl module requires file paths for client certificates. These temporary files are deleted immediately after the SSL context is created. Args: cert_bytes (bytes): The client certificate content in PEM format. key_bytes (bytes): The client private key content in PEM format. passphrase (Optional[bytes]): The passphrase for the private key, if any. Returns: ssl.SSLContext: The configured SSL context with client certificate.

We look for certificates and keys with the following order of priority: 1. Certificate and key specified by certificate_config.json. Currently, only X.509 workload certificates are supported. Args: certificate_config_path (str): The certificate_config.json file path. Returns: Tuple[bool, bytes, bytes, bytes]: A boolean indicating if cert, key and passphrase are obtained, the cert bytes and key bytes both in PEM format, and passphrase bytes.
