'Gets details for the latest upgrade performed on this application.
Returns information about the state of the latest application upgrade
along with details to aid debugging application health issues.
: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: :class:`ApplicationUpgradeProgressInfo
<azure.servicefabric.models.ApplicationUpgradeProgressInfo>`
