Consider add a second_node.py example

[frafra]

Examples are useful and they all work well, but there is no example about how to run more than one node (a second_node.py or additional_node.py example).

As an alternative, first_node.py could become a generic node which tries to bootstrap if a host and a port are specified.

Hey @frafra - both "get.py" and "set.py" run additional nodes, since running a node is necessary to interact with the network. I do take the point though that it might be a good idea to have a generalized script that could either be a long running bootstrap node or connect to an existing network. What if first_node.py was changed to just node.py, and then accepted an optional host/port argument. If the argument is omitted, then it would run as a bootstrap node. If the argument is given, then it will try to connect to that node and join its network. What do you think?

[frafra]

I think it would be great :)

@bmuller and @frafra I have created a PR and tried to implement the idea of a generalized node script. @bmuller can you please review it?
