d2f852a274 Aggregations: Add 'offset' option to date_histogram, replacing 'pre_offset' and 'post_offset' 
Add offset option to 'date_histogram' replacing and simplifying the previous 'pre_offset' and 'post_offset' options.
This change is part of a larger clean up task for `date_histogram` from issue #9062.

285ef0f06d Aggregations: Clean up response API for Aggregations 
This change makes the response API object for Histogram Aggregations the same for all types of Histogram, and does the same for all types of Ranges.
The change removes getBucketByKey() from all aggregations except filters and terms. It also reduces the methods on the Bucket class to just getKey() and getKeyAsString().
The getKey() method returns Object and the actual Type is returns will be appropriate for the type of aggregation being run. e.g. date_histogram will return a DateTime for this method and Histogram will return a Number.

052645903a Rest: remove status code from main action 
Today we give the HTTP status back within the HTTP response itself and within the JSON response as well:

```sh
curl localhost:9200/
```

```js
{
  "status" : 200,
  "name" : "Red Wolf",
  "version" : {
    "number" : "2.0.0",
    "build_hash" : "6837a61d8a646a2ac7dc8da1ab3c4ab85d60882d",
    "build_timestamp" : "2014-08-19T13:55:56Z",
    "build_snapshot" : true,
    "lucene_version" : "4.9"
  },
  "tagline" : "You Know, for Search"
}

060f963a8e Mappings: Remove allow_type_wrapper setting 
Before Elasticsearch 1.0, the type was allowed to be passed as the root
element when uploading a document.  However, this was ambiguous if the
mappings also contained a field with the same name as the type.  The
behavior was changed in 1.0 to not allow this, but a setting was added
for backwards compatibility.  This change removes the setting for 2.0.

ca4f27f40e Core: Added _shards header to all write responses. 
The header indicates to how many shard copies (primary and replicas shards) a write was supposed to go to, to how many
shard copies to write succeeded and potentially captures shard failures if writing into a replica shard fails.

For async writes it also includes the number of shards a write is still pending.

Closes #7994

20f7be378b Removed parent parameter from update request, because it is just sets the routing. 
The routing option should be used instead. The parent a child document points to can't be updated.

bc86796592 Core: Remove terms filter cache. 
This is our only cache which is not 'exact' and might allow for stalled results.
Additionally, a similar cache that we have and needs to perform lookups in other
indices in order to run queries is the script index, and for this index we rely
on the filesystem cache, so we should probably do the same with terms filters
lookups.

1959275622 Term Vectors: More consistent naming for term vector[s] 
We speak of the term vectors of a document, where each field has an associated
stored term vector. Since by default we are requesting all the term vectors of
a document, the HTTP request endpoint should rather be called `_termvectors`
instead of `_termvector`. The usage of `_termvector` is now deprecated, as
well as the transport client call to termVector and prepareTermVector.

Closes #8484

9ea25df649 Switch to murmurhash3 to route documents to shards. 
We currently use the djb2 hash function in order to compute the shard a
document should go to. Unfortunately this hash function is not very
sophisticated and you can sometimes hit adversarial cases, such as numeric ids
on 33 shards.

Murmur3 generates hashes with a better distribution, which should avoid the
adversarial cases.

Here are some examples of how 100000 incremental ids are distributed to shards
using either djb2 or murmur3.

5 shards:
Murmur3: [19933, 19964, 19940, 20030, 20133]
DJB:     [20000, 20000, 20000, 20000, 20000]

3 shards:
Murmur3: [33185, 33347, 33468]
DJB:     [30100, 30000, 39900]

33 shards:
Murmur3: [2999, 3096, 2930, 2986, 3070, 3093, 3023, 3052, 3112, 2940, 3036, 2985, 3031, 3048, 3127, 2961, 2901, 3105, 3041, 3130, 3013, 3035, 3031, 3019, 3008, 3022, 3111, 3086, 3016, 2996, 3075, 2945, 2977]
DJB:     [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 900, 900, 900, 900, 1000, 1000, 10000, 10000, 10000, 10000, 9100, 9100, 9100, 9100, 9000, 9000, 0, 0, 0, 0, 0, 0]

Even if djb2 looks ideal in some cases (5 shards), the fact that the
distribution of its hashes has some patterns can raise issues with some shard
counts (eg. 3, or even worse 33).

Some tests have been modified because they relied on implementation details of
the routing hash function.

5fe782b784 Indices API: Added GET Index API 
Returns information about settings, aliases, warmers, and mappings. Basically returns the IndexMetadata. This new endpoint replaces the /{index}/_alias|_aliases|_mapping|_mappings|_settings|_warmer|_warmers and /_alias|_aliases|_mapping|_mappings|_settings|_warmer|_warmers endpoints whilst maintaining the same response formats.  The only exception to this is on the /_alias|_aliases|_warmer|_warmers endpoint which will now return a section for 'aliases' or 'warmers' even if no aliases or warmers exist. This backwards compatibility change is documented in the reference docs.
