    Execute functional test "test_get_all_devices" alone
    
    Since [1], the functional tests are being executed in Ubuntu 22.04.
    The test "test_get_all_devices" is failing frequently, maybe because
    other tests are interfering and modifying the root namespace
    interface list.
    
    Because this test cannot be executed inside a temporary namespace,
    this patch moves the execution of this test to the section of
    "concurrency=1". That will ensure no other test interferes the
    result.
