 Summary: Enhance UpgradeIndexMergePolicy with additional options
 Key: LUCENE-7671
 URL: https://issues.apache.org/jira/browse/LUCENE-7671
 Project: Lucene - Core
  Issue Type: Improvement
Reporter: Keith Laban


Enhance UpgradeIndexMergePolicy to be a MergePolicy that can be used outside 
the scope the IndexUpgrader.

The enhancement aims to allow the UpgradeIndexMergePolicy to:

1) Delegate normal force merges to the underlying merge policy
2) Enable a flag that will explicitly tell UpgradeIndexMergePolicy when it 
should start looking for upgrades.
3) Allow new segments to be considered to be merged with old segments, 
depending on underlying MergePolicy.
4) Be configurable for backwards compatibility such that only segments needing 
an upgrade would be considered when merging, no explicit upgrades.
