thinking: Consider whether or not to use the WithBlock dial option

[meling]

Many of our examples use the WithBlock option to wait for client connections to be established. According to gRPC documentation, this is apparently an anit-pattern that may not be appropriate.

We need to understand how avoiding the WithBlock dial option will impact our use in combination with Gorums.

I think this might be part of a bigger problem: A config cannot be created if some of the nodes are not up and running.

I have linked a pull request that will create a config regardless of the status of the node (it will, however, try to connect to the node initially). Instead, it will try to connect to nodes (that are offline) for each message that is supposed to be sent to the nodes.

The solution passes all tests and have been tested "live" (i.e. in an actual implementation). It also removes the need for using WithBlock().
