scheduler: prevent -Inf in spread scoring (#17198) When spread targets have a percent value of zero it's possible for them to return -Inf scoring because of a float divide by zero. This is very hard for operators to debug because the string "-Inf" is returned in the API and that breaks the presentation of debugging data. Most scoring iterators are bracketed to -1/+1, but spread iterators do not so that they can handle greatly unbalanced scoring so we can't simply return a -1 score without generating a score that might be greater than the negative scores set by other spread targets. Instead, track the lowest-seen spread boost and use that as the spread boost for any cases where we'd divide by zero. Fixes: #8863
