* Deprecate set but unused Status property in favour of ProgressDescription. * Deprecate set but unused TitlePlan property. * Deprecated property Title in favour of ProgressDescription. * Removed unused plan RebootHostPlanAction. * Updated event declaration. * Removed property Visible. The plan is to have the actions log their history as soon as some is available. * Reworked the logging for the plan actions. The main change is the replacement of the ProgressDescription with a stack where all the steps of an action are stored, i.e. the action is responsible for its history, not the worker running it. * Lock the progress history before accessing it. * Better handling of error logging and user cancellation.
