Setup Clustered Controller For Switches
[Documentation] The idea of this keyword is to setup clustered controller and to be more or less sure that the role is filled correctly. The problem is when
... more controllers are being set up at once, the role shown in Controller ovsdb table is not the same as we can see from wireshark traces.
... Now we set disconnected controllers and we will connect them expecting that the first connected controller will be master.
