Add configuration options to control maximum size of segments
-------------------------------------------------------------

                 Key: HSEARCH-754
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-754
             Project: Hibernate Search
          Issue Type: New Feature
          Components: documentation, engine, optimizer
            Reporter: Sanne Grinovero
            Assignee: Sanne Grinovero
             Fix For: 4.0


org.apache.lucene.index.LogByteSizeMergePolicy exposes configuration settings which are currently not selectable in Hibernate Search:
 - minMergeSize
 - maxMergeSize
 - maxMergeSizeForOptimize

being able to limit the size of a segment is very useful to get best performance out of the Infinispan Lucene Directory: performance degrades due to the need for readlocks when the size of a segment is higher than the maximum chunk size in Infinispan.

Readlocks are automatically engaged when needed, so this has no functional impact but is quite noticeable in terms of performance.
