Implement a new CLI command 'del server'. It can be used to removed a dynamically added server. Only servers in maintenance mode can be removed, and without pending/active/idle connection on it. Add a new reg-test for this feature. The scenario of the reg-test need to first add a dynamic server. It is then deleted and a client is used to ensure that the server is non joinable. The management doc is updated with the new command 'del server'.
