Ticket #622: restrict server to nano profile scope by default

Closes #622 (closed) Restrict server to nano profile scope by default. If WITH_NANO_EXTENDED != 0 during compilation, the extended scope (partial subscription implementation) is activated. Default CI runs with WITH_NANO_EXTENDED = 1, a nightly CI runs with WITH_NANO_EXTENDED = 0. A test has been added into toolkit_test_client to check the subscription service is not available when WITH_NANO_EXTENDED = 0 (or undefined).
