Option to not render hostnames in the node map

[tobami]

Each node in the generated graph has one line for the hostname and one for each role.

We could add an option to not show the hostname. That is useful if you are just interested in the logical architecture and not in the specific node configuration that currently exists. It should made graphs more compact

Sure, it might be nice, but I must say I'm not convinced the benefit would justify the work needed to implement this...
