[jira] [Created] (LUCENE-7010) Create MergePolicyWrapper

Shai Erera created LUCENE-7010:
----------------------------------

             Summary: Create MergePolicyWrapper
                 Key: LUCENE-7010
                 URL: https://issues.apache.org/jira/browse/LUCENE-7010
             Project: Lucene - Core
          Issue Type: Improvement
          Components: core/index
            Reporter: Shai Erera
            Assignee: Shai Erera


We currently have two MergePolicy implementations that are wrappers around another MP: {{SortingMergePolicy}} and {{UpgradeIndexMergePolicy}}. A {{MergePolicyWrapper}} will simplify building additional such wrapping MPs by delegating all method calls to the wrapped instance, and allowing implementations to override only what they need.

Also, this issue removes the {{final}} modifier from MP public methods so that they can be delegated properly. See LUCENE-7008 for a test failure that uncovered this issue.
