A bit bulky but I don't have a better idea ;-)

> In OAK-4732 the 50th percentile of the last 1000 commits is used as wait time before
returning the current root. In order to parametrise the value of the percentile, it would
be nice to have a new feature flag, e.g. {{oak.scheduler.head.lockWaitPercentile}}. Setting
it to {{0}} would basically disable this. Setting it to a different value might be interesting
in future experiments.
