New functions 'deactivate' and 'reactivate' are added to ered_client.
When a node is removed from the cluster, the client to that node is first deactivated, then stopped after some time. When the client is deactivated, it replies to commands immediately with {error, node_deactivated}.
If the node comes back to the cluster and the client to this node is not yet stopped, the client is reactivated and ered recovers faster than if it would have to start a new client to that node.
