  1. Reduce memory pressure when sending large terms queries to Elasticsea… 

    …rch.

When users send large `terms` query to Elasticsearch, every value is stored in
an object. This change does not reduce the amount of created objects, but makes
sure these objects die young by optimizing the list storage in case all values
are either non-null instances of Long objects or BytesRef objects, which seems
to help the JVM significantly.
