Alex Ksikes 35f55608cc MLT Field Query: remove it from master

To simplify code maintenance we should deprecate it in 1.4 and remove it in
2.0.

== Breaking changes in 2.0
This section discusses the changes that you need to be aware of when migrating
your application to Elasticsearch 2.0.
=== Indices API
The <<alias-retrieving, get alias api>> will, by default produce an error response
if a requested index does not exist. This change brings the defaults for this API in
line with the other Indices APIs. The <<multi-index>> options can be used on a request
to change this behavior
=== Partial fields
Partial fields were deprecated since 1.0.0beta1 in favor of <<search-request-source-filtering,source filtering>>.
=== More Like This Field
The More Like This Field query has been removed in favor of the <<query-dsl-mlt-query, More Like This Query>>
restrained set to a specific `field`.
