The current `tee` command appends a definition to
`/etc/apt/sources.list.d/elastic-{version}.list`.
This can lead to duplicate lines and significantly slow apt-get
operations.
This updates the command to overwrite rather than append.
This commit fixes the list dangling indices response.
The dangling_indices array is an array of objects
that represent aggregated dangling index information

When a new cluster starts, the HTTP layer becomes ready to accept incoming
requests while the basic license is still being populated in the background.
When a get license request comes in before the license is ready, it can get
404 error. This PR fixes it by either wrap the license check in assertBusy or
ensure the license is ready before perform the check.
This is a backport for both #60498 and #60573
Plugin discovery documentation contained information about installing
Elasticsearch 2.0 and installing an oracle JDK, both of which is no
longer valid.
While noticing that the instructions used cleartext HTTP to install
packages, this commit replaces HTTPs links instead of HTTP where possible.
In addition a few community links have been removed, as they do not seem
to exist anymore.

* SQL: Add option to provide the delimiter for the CSV format (#59907)
* Add option to provide the delimiter to the CSV fmt
This adds the option to provide the desired character as the separator
for the CSV format (the default remains comma).
A set of characters are excluded though - like CR, LF, `"` - to avoid
slipping onto the CSV-dialects slope. The tab is also forbidden, the
user needs to choose the "tsv" format explicitely.
Update the doc to make it clear that the textual CSV, TSV and TXT
formats pass the cursor back to the user through the Cursor HTTP header.

* Java8 fixes
- replace Set#of();
- URLDecoder#decode() requires a string (vs a charset) as 2nd arg.
Changes:
* Adds the `number_of_routing_shards` index setting to index modules docs.
* Updates the split API docs to mention that `number_of_routing_shards`
is a static setting.
Today there are a few places in the transport layer docs where we talk
about communication between nodes _within a cluster_. We also use the
transport layer for remote cluster connections, and these statements
also apply there, but this is not clear from today's docs. This commit
generalises these statements to make it clear that they apply to remote
cluster connections too.
It also adds a link from the docs on configuring TCP retries to the
(deeply-buried) docs on preserving long-lived connections.
This feature adds a new `fields` parameter to the search request, which
consults both the document `_source` and the mappings to fetch fields in a
consistent way. The PR merges the `field-retrieval` feature branch.
Addresses #49028 and #55363.
Transport connections between nodes remain in place until one or other
node shuts down or the connection is disrupted by a flaky network.
Today it is very difficult to demonstrate that transient failures and
cluster instability are caused by the network even though this is often
the case. In particular, transport connections open and close without
logging anything, even at `DEBUG` level, making it very hard to quantify
the scale of the problem or to correlate the networking problems with
external events.
This commit adds the missing `DEBUG`-level logging when transport
connections open and close, and also tracks the total number of
transport connections a node has opened as a measure of the stability of
the underlying network.
* Adds table with icons for simplicity.
* Updating table for clarity.
* Changing table formatting and incorporating more feedback.
* Changing table alignment.
Keepalive options are not well-documented (only in transport section, although also available at http and network level).

keepalives tell any intermediate devices that the connection remains alive, which helps with overzealous firewalls that are
killing idle connections. keepalives are enabled by default in Elasticsearch, but use system defaults for their
configuration, which often times do not have reasonable defaults (e.g. 7200s for TCP_KEEP_IDLE) in the context of
distributed systems such as Elasticsearch.
This PR sets the socket-level keep_alive options for network.tcp.{keep_idle,keep_interval} to 5 minutes on configurations
that support it (>= Java 11 & (MacOS || Linux)) and where the system defaults are set to something higher than 5
minutes. This helps keep the connections alive while not interfering with system defaults or user-specified settings
unless they are deemed to be set too high by providing better out-of-the-box defaults.
