We should open up the node to the world when it's as ready as possiblAt the moment we open up the transport service before the local node has been fully initialized. This causes bug as some data structures are not fully initialized yet. See for example #16723.
Sadly, we can't just start the TransportService last (as we do with the HTTP server) because the ClusterService needs to know the bound published network address for the local DiscoveryNode. This address can only be determined by actually binding (people may use, for example, port 0). Instead we start the TransportService as late as possible but block any incoming requests until the node has completed initialization.
A couple of other cleanup during start time:
1) The gateway service now starts before the initial cluster join so we can simplify the logic to recover state if the local node has become master.
2) The discovery is started before the transport service accepts requests, but we only start the join process later using a dedicated method.

This commit removes the system property "es.useLinkedTransferQueue" that
defaulted to false and was used to control the queue implementation used
in a few places.
Closes#16786
This commit adds a check on startup for G1 GC while running on early
versions of HotSpot version 25. This is to prevent potential data
corruption issues that can occur on those versions.

Java NIO has the notion of gathering writes. These are writes that
gather data from multiple buffers into a single channel. These gathering
writes in Netty have been enabled by default with the possibility to
disable them using "es.netty.gathering". This flag was added in case
having gathering writes on by default did not work out. We have not
published this ability and sufficient time has passed to render
judgement that using gathering writes is okay.
Closes#16774
Expose http address in cat/nodes and cat/nodeattrs APIs
We expose a lot of information like IP address and port but never
expose the http address/ip:port in the CAT API. It's nice to have it
there too since otherwise json parsing is required to get this information

Elasticsearch should reject ids that are this long, to ensure a document
always remains retrievable for clients that impose a maximum URI length

Most elements in SearchSourceBuilder (e.g. aggs, queries) write their top-level
ParseField name in toXContent(), while HighlightBuilder used to do it in
its own toXContent() method. Moved this up so SeachSourceBuilder for consistency.
Today we might start a node and some of the paths might not have the
required permissions. This commit goes through all data directories as
well as index, shard and state directories and ensures we have write access.
To make this work across all OS etc. we are trying to write a real file
and remove it again in each of those directories
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
This commit tries to 'guess' if a user starts a node in production by
checking if any network host is configured. If that is the case soft-limits
that are only logged otherwise are enforced like number of open file descriptors.
Closes#16727
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
