REST Update Settings API should not take timeout and master_timeout as index parameters
closes #4692
Geo clean Up
============
The default unit for measuring distances is *MILES* in most cases. This commit moves ES
over to the *International System of Units* and make it work on a default which relates
to *METERS* . Also the current structures of the `GeoBoundingBox Filter` changed in
order to define the *Bounding* by setting abitrary corners.

Distances
---------
Since the default unit for measuring distances has changed to a default unit
`DistanceUnit.DEFAULT` relating to *meters*, the **REST API** has changed at the
following places:

  * `ScriptDocValues.factorDistance()` returns *meters* instead of *miles*
  * `ScriptDocValues.factorDistanceWithDefault()` returns *meters* instead of *miles*
  * `ScriptDocValues.arcDistance()` returns *meters* instead of *miles*
        one might use `ScriptDocValues.arcDistanceInMiles()`
  * `ScriptDocValues.arcDistanceWithDefault()` returns *meters* instead of *miles*
  * `ScriptDocValues.distance()` returns *meters* instead of *miles*
        one might use `ScriptDocValues.distanceInMiles()`
  * `ScriptDocValues.distanceWithDefault()` returns *meters* instead of *miles*
        one might use `ScriptDocValues.distanceInMilesWithDefault()`
  * `GeoDistanceFilter` default unit changes from *kilometers* to *meters*
  * `GeoDistanceRangeFilter` default unit changes from *miles* to *meters*
  * `GeoDistanceFacet` default unit changes from *miles* to *meters*

Geo Bounding Box Filter
-----------------------
The naming of the GeoBoundingBoxFilter properties allows to set arbitrary corners
(see #4084) namely `top_right`, `top_left`, `bottom_right` and `bottom_left`. This
change also includes the fields `topRight` and `bottomLeft` Also it is be possible to
set the single values by using just `top`, `bottom`, `left` and `right` parameters.

Closes #4515, #4084

[REST tests] Improved DoSection behaviour

No error wa previously thrown when a catch section was specified and a the rest call returned no error
Also, moved the catch:request on top to avoid even sending requests in that case
add MockPageCacheRecycler in test jar

MockPageCacheRecycler is missing in test jar which makes failing tests when using
test jar in plugins:

Closes #4694.
Replaced the multi-field type in favour for the multi fields option that can be set on any core field.

When upgrading to ES 1.0 the existing mappings with a multi-field type automatically get replaced to a core field with the new `fields` option.

If a `multi_field` type-ed field doesn't have a main / default field, a default field will be chosen for the multi fields syntax. The new main field type
will be equal to the first `multi_field` fields' field or type string if no fields have been configured for the `multi_field` field and in both cases
the default index will not be indexed (`index=no` is set on the default field).

If a `multi_field` typed field has a default field, that field will replace the `multi_field` typed field.

Closes to #4521
Add new option `min_doc_count` to terms and histogram aggregations.

`min_doc_count` is the minimum number of hits that a term or histogram key
should match in order to appear in the response.

`min_doc_count=0` replaces `compute_empty_buckets` for histograms and will
behave exactly like facets' `all_terms=true` for terms aggregations.

Fix YAML in test/indices.open/20_multiple_indices.yaml
Default stopwords list should be `_none_` for all but language-specific analyzers

`standard_html_strip` and `pattern` analyzer support stopwords which are
set to the default `english` stopwords by default. Those analyzers
should not use stopwords by default since they are language neutral

Added test with awaits annotation that exposes a merge mapping issue.

 If the path_type is set to `just_name` in a multi_field typed field and that field is updated (for example another multi field is added) then if the path isn't specified again the path_type isn't taken into account and full path names are generated.

[SPEC] Updated cluster.node_stats and indices.stats
Standardized use of “*_length” for parameter names rather than “*_len”.
Java Builder apis drop old “len” methods in favour of new “length”
Rest APIs support both old “len: and new “length” forms using new ParseField class to a) provide compiler-checked consistency between Builder and Parser classes and
b) a common means of handling deprecated syntax in the DSL.
Documentation and rest specs only document the new “*length” forms
