create testnet for verifying chain_id change
We need a testnet we can use for verifying that applications handle the chain-id change that happens at HF24. We'll want to give applications multiple chances to test the changeover, so we should configure the testnet to reset itself periodically. We could have the testnet reset itself on odd hours, and schedule the hardforks to happen on even hours. That way we get several chances to test each day.
Create a script that sets the STEEM_HF24_TIME environment variable for an hour in the future, launches a testnet, waits two hours, then terminates the testnet and repeats.
