+Don't manage services scheduling while upgrade
+----------------------------------------------

+before and after upgrade procedure.

+If 'manage_service_maintenance: true' or not present - default behavior, disable services
+before upgrade and enable it after upgrade.
+If 'manage_service_maintenance: false' - don't disable and don't enable upgraded services
+scheduling before and after upgrade.
