of the policy defaults as required by the service and use the policies in the
Configuration to construct the pipeline correctly, as well as inserting any
unexposed/non-configurable policies.
:ivar headers_policy: Provides parameters for custom or additional headers to be sent with the request.
:ivar proxy_policy: Provides configuration parameters for proxy.
:ivar redirect_policy: Provides configuration parameters for redirects.
:ivar retry_policy: Provides configuration parameters for retries in the pipeline.
:ivar custom_hook_policy: Provides configuration parameters for a custom hook.
:ivar logging_policy: Provides configuration parameters for logging.
:ivar http_logging_policy: Provides configuration parameters for HTTP specific logging.
:ivar user_agent_policy: Provides configuration parameters to append custom values to the
User-Agent header.
:ivar authentication_policy: Provides configuration parameters for adding a bearer token Authorization
header to requests.
:ivar request_id_policy: Provides configuration parameters for adding a request id to requests.
