* mandos-ctl: Where the clients names "foo" and "barbar" do not refer to the actual mock clients in the TestCommand class, change all occurrences of these names to "client1" and "client2" (or just "client" when only one is used) . Also change all test doubles to use correct terminology; some things called mocks are actually stubs or spies, and rename all true mocks to have "mock" in their names. Also eliminate duplicate values in tests; derive values from previously defined values whenever possible.
