Named wildcards were not always properly replaced with proper values by PathTrie.
Delete index (curl -XDELETE localhost:9200/*) worked anyway as the named wildcard is the last path element (and even if {index} didn't get replaced with '*', the empty string would have mapped to all indices anyway). When the named wildcard wasn't the last path element (e.g. curl -XPOST localhost:29200/*/_close), the variable didn't get replaced with the current '*' value, but with the empty string, which leads to an error as empty index is not allowed by open/close index.

The new internal get index settings api is more efficient when it comes to sending the index settings from the master to the client via the
Also the get index settings support now all the indices options.

The FVH was throwing away some boosts on queries stopping a number of
ways to boost phrase matches to the top of the list of fragments from
working.
The plain highlighter also doesn't work for this but that is because it
doesn't support the concept of the same term having a different score at
different positions.
Also update documentation claiming that FHV is nicer for weighing terms
found by query combinations.

Important: This breaks backwards compatibility with 0.90
* Removed endpoints: /_cluster/nodes, /_cluster/nodes/nodeId1,nodeId2
* Disallow usage of parameters, but make required metrics part of URI
* Changed NodesInfoRequest to return everything by default
* Fixed NPE in NodesInfoResponse
Closes#4055
Instead of specifying what kind of data should be filtered, this commit
streamlines the API to actually specify, what kind of data should be displayed.
This makes its behaviour similar to the other requests, like NodeIndicesStats.
A small feature has been added as well: If you specify an index to select on, not
only the metadata, but also the routing tables are filtered by index in order
to prevent too big cluster states to be returned.
Also the CAT apis have been changed to only return the wanted data in order to keep
network traffic as small as needed.
Tests for the cluster state API filtering have been added as well.
Note: This change breaks backwards compatibility with 0.90!
Closes#4065
Added a long-based representation of GeoHashes to GeoHashUtils for fast evaluation in aggregations.
The new BucketUtils provides a common heuristic for determining the number of results to obtain from each shard in "top N" type requests.

Fixes#4451
Date fields without date (HH:mm:ss, for example) are parsed as time on Jan 1, 1970 UTC. However, before this change partial dates without year (MMM dd HH:mm:ss, for example) were parsed as as days of they year 2000. This change makes all partial dates to be treated based on year 1970. This is breaking change - before this change "Dec 15, 10:00:00" in most cases was parsed (and indexed) as "2000-12-15T10:00:00Z". After this change, it will be consistently parsed and indexed as "1970-12-15T10:00:00Z"
Refactor cache recycling so that it only caches large arrays (pages) that can
later be used to build more complex data-structures such as hash tables.
- QueueRecycler now takes a limit like other non-trivial recyclers.
- New PageCacheRecycler (inspired of CacheRecycler) has the ability to cache
byte[], int[], long[], double[] or Object[] arrays using a fixed amount of
memory (either globally or per-thread depending on the Recycler impl, eg.
queue is global while thread_local is per-thread).
- Paged arrays in o.e.common.util can now optionally take a PageCacheRecycler
to reuse existing pages.
- All aggregators' data-structures now use PageCacheRecycler:
- for all arrays (counts, mins, maxes, ...)
- LongHash can now take a PageCacheRecycler
- there is a new BytesRefHash (inspired from Lucene but quite different,
still; for instance it cheats on BytesRef comparisons by using Unsafe)
that also takes a PageCacheRecycler
Close#4557
Adding a small value to the threshold prevents weight deltas that are
very very close to the threshold to not trigger relocations. These
deltas can be rounding errors that lead to unnecessary relocations. In
practice this might only happen under very rare circumstances.
In general it's a good idea for the shard allocator to be a bit
more conversavtive in terms of rebalancing since in general relocation
costs are pretty high.
