This commit removes the es.max-open-files flag as the same information
can be obtained from the cluster nodes info API, and is warn logged on
startup if it's set too low anyway.
Closes#16757
Today we have the notion of a snapshot inside Version.java which makes
releasing complicated since to do a release Version.java must be changed.
This commit removes all notions of snapshot from the code and allows to
switch between snapshot and release build by specifying a system property on
the build. For instance running:
```
gradle run -Dbuild.snapshot=false
```
will build and package a release build while the default always
builds snapshots. Calls to the main rest action will still get the snapshot
information rendered out with the response.
This was changed when adding the text field in an attempt to clean up
how analyzers are set. Unfortunately this change was not safe for the
string field given that it can also represent keywords.
Also renamed histogram.AbstractBuilcer to AbstractHistogramBuilder, range.AbstractBuilder to AbstractRangeBuilder and org.elasticsearch.search.aggregations.pipeline.having to org.elasticsearch.search.aggregations.pipeline.bucketselector
Function Score Query now checks the type of token that we are parsing, which makes parsing stricter and allows to throw useful errors in case the json is malformed. It also makes code more readable as in what gets parsed when.
Closes#16583
This commit updates the OrdinalsBuilder and GeoPoint FieldData loader to work with the new PREFIX_ENCODING introduced in lucene-5.5.0. Backcompat is included to support legacy encoding types.

After #15776 got in, we don't need these copy constructors anymore. When we used to copy requests it was to make sure that headers and context were copied from the parent requests (e.g. index/delete as part of update). This is not a problem anymore.
The current logic for doing recovery from a source to a target shourd is tightly coupled with the underlying network pipes. This changes decouple the two, making it easier to add unit tests for shard recovery that doesn't involve the node and network environment.
On top that, RecoveryTarget is renamed to RecoveryTargetService leaving space to renaming RecoveryStatus to RecoveryTarget (and thus avoid the confusion we have today with RecoveryState).
Correspondingly RecoverySource is renamed to RecoverySourceService.
Closes#16605
