Thanks @JeancarloBarrios ! I've added parametrization of node count here fe5d0bd

For the initial state my suggestion for now is to rely on the CLI to create state init scripts, mainly because the dynamic creation of the keys between on each start makes the genesis file generation a bit more complex. As this devenet gets more usage we can evaluate if it's worth adding tooling around genesis file state generation for better developer ergonomics
