'Starts rolling back the currently on-going upgrade of an application
in the Service Fabric cluster.
Starts rolling back the current application upgrade to the previous
version. This API can only be used to rollback the current
in-progress upgrade that is rolling forward to new version. If the
application is not currently being upgraded use
StartApplicationUpgrade API to upgrade it to desired version
including rolling back to a previous version.
:param application_id: The identity of the application. This is
typically the full name of the application without the \'fabric:\' URI
scheme.
:type application_id: str
:param timeout: The server timeout for performing the operation in
seconds. This specifies the time duration that the client is willing
to wait for the requested operation to complete. The default value
for this parameter is 60 seconds.
:type timeout: long
:param dict custom_headers: headers that will be added to the request
:param bool raw: returns the direct response alongside the
deserialized response
:param operation_config: :ref:`Operation configuration
overrides<msrest:optionsforoperations>`.
:rtype: None
:rtype: :class:`ClientRawResponse<msrest.pipeline.ClientRawResponse>`
