Support joining a distributed environment.
------------------------------------------

                 Key: LUCENE-3759
                 URL: https://issues.apache.org/jira/browse/LUCENE-3759
             Project: Lucene - Java
          Issue Type: Improvement
          Components: modules/join
            Reporter: Martijn van Groningen


Add two more methods in JoinUtil to support joining in a distributed manner.
* Method to retrieve all from values.
* Method to create a TermsQuery based on a set of from terms.

With these two methods distributed joining can be supported following these steps:
# Retrieve from values from each shard
# Merge the retrieved from values. 
# Create a TermsQuery based on the merged from terms and send this query to all shards.
