Internally we already kept track of whether a data stream is replicated by CCR.
It is part of the `DataStream` class. This just adds it to the xcontent serialization
of the get data stream api response class.

This PR changes uses of transient cluster settings to
persistent cluster settings.
The PR also deprecates the transient settings usage.
Relates to #49540
To switch an index's lifecycle policy, you must first remove the existing
policy. Otherwise, phase execution for the index may silently fail.
Closes#70151
This commit adds support for system data streams and also the first use
of a system data stream with the fleet action results data stream. A
system data stream is one that is used to store system data that users
should not interact with directly. Elasticsearch will manage these data
streams. REST API access is available for external system data streams
so that other stack components can store system data within a system
data stream. System data streams will not use the system index read and
write threadpools.
Adds an important admonition for the built-in `metrics-*-*` and `logs-*-*` index
templates.
Updates several put index template snippets to include a priority.
Uses `my-data-stream` in place of `logs` for data stream examples.
This provides a more intuitive experience for users that copy/paste
their own values into snippets.
Removes the `@timestamp` field mapping from several data stream index
template snippets.
With #59317, the `@timestamp` field defaults to a `date` field data type
for data streams.
This makes the data_stream timestamp field specification optional when
defining a composable template.
When there isn't one specified it will default to `@timestamp`.
Replaces `composable index template` and `composable template` with
`index template` throughout data stream-related docs.
`Composable index template` is only used to contrast with legacy index
templates.
With #58096, data streams now track the timestamp field mapping outside
of the template associated with the stream. This means you can no longer
update the timestamp field mapping using template changes.
This updates the associated data stream docs.
