Similar to the global cluster wide disable allocation flags, allow to set those on a specific index by updating its settings. The keys are the same as the cluster one, except they start with an index, for example: index.routing.allocation.disable_allocation set to true.

The branches used in the score method can be moved into the
scorer call and be essentially a constant operation rather than
a linear operation depending on the number of parent docs.
Older OpenSUSE distributions do not ship with systemd and therefore are
using chkconfig, but do not have their scripts placed at /etc/init.d/
This patch is more defensive and adds additional checks in the postinstall
script to prevent aborted post install scripts, which makes the RPM
uninstallable.
when resolving empty settings values, their value should be removed, for example, when using ${env.ENV_VAR}, and ENV_VAR is not set, then the setting should be removed
This commit allows to set custom headers in HTTP responses (like
setting the WWW-Authenticate header for basic auth) by adding
RestRequest.addHeader() method.

To get the history right: This is based on PR #2723
Update requests can now be put in the bulk api. All update request options are supported.
Example usage:
```
curl -XPOST 'localhost:9200/_bulk' --date-binary @bulk.json
```
Contents of bulk.json that contains two update request items:
```
{ "update" : {"_id" : "1", "_type" : "type1", "_index" : "index1", "_retry_on_conflict" : 3} }
{ "doc" : {"field" : "value"} }
{ "update" : { "_id" : "0", "_type" : "type1", "_index" : "index1", "_retry_on_conflict" : 3} }
{ "script" : "counter += param1", "lang" : "js", "params" : {"param1" : 1}, "upsert" : {"counter" : 1}}
```
The `doc`, `upsert` and all script related options are part of the payload. The `retry_on_conflict` option is part of the header.
Closes#2982
Before this change, the GetField#getValue() method was returning a list of values of a multivalued fields if the field values were obtained from source or if the field was stored and real-time get was used. If the field was stored but non-realtime get was used, GetField#getValue() was returning only the first element and the GetField#getValues() was returning a list of elements. This change makes behavior consistent. GetField#getValue() now always returns only the first value of the field and GetField#getValues() returns the entire list.
Typically, the main reason a reroute allocation command with allow_primary is enabled, is to force create an empty new shard because a shard (and its replicas) were lost. This can't be done today because the shard expects to have a valid index where its allocated, we need to clear its post allocation flag to make sure it is allowed to create a fresh index.
Lucene provides a set of statistics that depend on the codec / postingsformat
as well as on the index options used when the field is created / indexed.
If a certain stats value is not available lucene return `-1` instead of the
correct value. We need to ensure that those values are encoded correctly if
we try to write vLongs as well as when we aggregate those values.
Closes#3012
NgramTokenizer and NGramTokenFilter are broken with a version < 4.2
We should still support these filters but should prevent the StringIOOB
exceptions. Adding these fitlers for the FragmentBuilderHelper will
allow seamless highlighting on fields indexed with those tokenizers or
tokenfilters
Lucenes span queries are a different family than 'ordinary' queries
in lucene. Spans only work with other spans such that smart query
wrapping doesn't work with span queries at all ie. we can't wrap
in filtered query.
Closes#2994
Today an analysis chain with broken tokenfilters or tokenizers like
WordDelimiterFilter might produce somewhat broken term vectors that cause
`StringIndexOutOfBoundsExceptions` if FastVectorHighlighter is used
since the positions / offsets contract is violated and offsets of highlight
tokens are not increasing but decreasing even if their positions are increasing.
Yet, if we detect such a situation we can resort the tokens which might cause
somewhat odd highlights but doesn't fail hard with a StringIndexOOBException.
Closes#3006
All index meta data API's have urgent priority when it comes to cluster state updates. We'd like to remove indices asap to avoid things like unnecessary shards relocations
This Lucene Release introduced a new API on DocIdSetIterator that requires each
implementation to return a `cost` upperbound as a function of the iterated documents.
This API allows for several optimizations during query execution especially in
Conjunction and Disjunction Queries with min_should_match set.
Closes#2990
Allow to get the source directly using a specific REST endpoint without any additional content around it, the endpoint is `{index}/{type}/{id}/_source`.
Note, HEAD now also support the _source endpoint.
closes#2993, closes#2995
BytesRefOrdValComparator starts at 1 and ends at maxOrd - 1. Yet, numOrd is defined
as maxOrd - 1 excluding the 0 ord.
This causes wrong sort ords when the bottom of the queue is compared to the next
segment and the greatest term in the new segment is in-fact less than the current
queue bottom. If that is true we treat the values as equal and never include the right
value into the queue.
