Update/Add state for non-Rancher initiated cluster updates

[valaparthvi]

Sometimes there are non-Rancher initiated updates triggered by the console, this information is logged in the deployment logs, but there is no way to know if that is the case otherwise.

It would make sense to update the cluster state, or add a new field to indicate non-rancher initiated update is in progress.
