Enhance PictureViewsGenerationWork to be able to disable listeners before save

PictureViewsGenerationWork is explicitely disabling some listeners before saving the document

        workingDocument.putContextData("disableNotificationService", Boolean.TRUE);
        workingDocument.putContextData("disableAuditLogger", Boolean.TRUE);
        workingDocument.putContextData(VersioningService.DISABLE_AUTO_CHECKOUT, Boolean.TRUE);
        workingDocument.putContextData(DISABLE_PICTURE_VIEWS_GENERATION_LISTENER, Boolean.TRUE);
        session.saveDocument(workingDocument);

When a project defines custom listeners, it would be interesting to have a hook, like a beforeSave method, in this class to disable them. And a custom project could only overwrite this method instead of overwriting the complete class.

PS: what do we want to do with the BAF action RecomputeViewsAction which replaces PictureViewsGenerationWork since 11.x ?
