As part of Secure RBAC work, support for system users(eg. system admin) is being added. However current default format does not include the system scope information so we can't determine whether the context is non-scoped or system-scoped. This change updates the default logging_user_identity_format so that system scope is logged by default. Change-Id: I7982cdb280599fb38362eb837cb527592267b91f
