Adrien Grand 703dbff83d Index field names of documents. ...

The `exists` and `missing` filters need to merge postings lists of all existing
terms, which can be very costly, especially on high-cardinality fields. This
commit indexes the field names of a document under `_field_names` and reuses it
to speed up the `exists` and `missing` filters.

This is only enabled for indices that are created on or after Elasticsearch
1.3.0.
