Add an experiment to shorten the bandsteering delay.

If WifiShortBandsteeringDelay is active, bandsteering will reject
candidate STAs for only 1 second, rather than 10.  This is an
imperfect but very simple-to-implement approximation of what we really
want, which is to reject candidates only once.  If the results are
promising, a follow-up may implement this properly.
