The library "nose", used for unit testing, is removed. This library is in maintenance mode and is not compatible with Python3.10 [1]. Now all checks are implemented using "unittest". The methods are not loaded in realtime into the test case execution; instead of this, this patch uses "testscenarios.WithScenarios", that allows to execute the same test with different defined scenarios. NOTE: "BgpSpeakerTestBase" tests are disable temporarily. It is needed to configure "docker" in the system in order to execute them.
