TieredMergePolicy should expose control over how aggressively segments with deletions are targeted

---------------------------------------------------------------------------------------------------

                 Key: LUCENE-3210
                 URL: https://issues.apache.org/jira/browse/LUCENE-3210
             Project: Lucene - Java
          Issue Type: Improvement
          Components: core/index
            Reporter: Michael McCandless
            Assignee: Michael McCandless
            Priority: Minor
             Fix For: 3.3, 4.0


TMP today always does a linear pro-rating of a merge's score according to what pctg of the
documents are deleted; I'd like to 1) put a power factor in (score is multiplicative), and
2) default it to stronger favoring of merging away deletions.
