In this commit, we replace the existing min/max duration system with a single field that expresses the expected duration of a lease. Note that we've left some of the exiting logic in place that select a duration from a bid in an attempt to make this more of a "soft fork" which will allow any existing orders to be cleared out as normal before we switch over. Once we add multiple durations (this commit assumes a single duration), we'll need to modify the verification logic to be able to handle multiple clearing prices for a given batch.
