cover_SUITE:reconnect/1: Let the other side initiate the disconnect
The reconnect/1 test starts another node and takes down the connection to it for a while. However, it has been in observed in our daily builds that sometimes a "spontaneous" re-connection occurs. I think that it because of the call to rpc:cast/3 which internally will set the group leader for the remote process to a process on the test_server node. It seems that sometimes the group_leader/2 call will re-establish the connection. Unfortunately, I have not been able to force this to happen by inserting delays in the rpc module, so it it still just an hypothesis. However, letting the other node do the disconnection does seem to fix the problem and intuitively that should be safer way to do it because the group_leader/2 call and the disconnection will be executed sequentially on the same node instead of concurrently from two different nodes.
