[Feature] Allow to stop network at specific block

[piwonskp]

For benchmarking or any kind of activity that involves comparing networks it would be very handy to be able to specify a configuration that allows to stop the network. There may be multiple conditions on which the network may be stopped.

The most useful conditions to stop the network as I see it:

• At a specific block number
• After a certain amount of time

Such network could then return the result by printing a report to stdout, saving in a file or keeping grafana container up so it's accessible.
