LUCENE-8246: Allow to customize the number of deletes a merge claims
With the introduction of soft deletes no every merge claims all documents
that are marked as deleted in the segment readers. MergePolicies still
need to do accurate accounting in order to select segments for merging
and need to decide if segments are merged. This change allows the
merge policy to customize the number of deletes a merge of a segment
claims.
