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`.

separate pivot from the indexer and introduce an abstraction layer, pivot becomes a function.
Foundation to add more functions to transform.
piggy backed fixes:
- when running geo tile group_by it could fail due to query clause limit (unreleased)
- new style page size using settings was not validating limit of 10k (7.8)
Backport of #59076 to 7.x branch.
The commit makes the following changes:
* The timestamp field of a data stream definition in a composable
index template can only be set to '@timestamp'.
* Removed custom data stream timestamp field validation and reuse the validation from `TimestampFieldMapper` and
instead only check that the _timestamp field mapping has been defined on a backing index of a data stream.
* Moved code that injects _timestamp meta field mapping from `MetadataCreateIndexService#applyCreateIndexRequestWithV2Template58956(...)` method
to `MetadataIndexTemplateService#collectMappings(...)` method.
* Fixed a bug (#58956) that cases timestamp field validation to be performed
for each template and instead of the final mappings that is created.
* only apply _timestamp meta field if index is created as part of a data stream or data stream rollover,
this fixes a docs test, where a regular index creation matches (logs-*) with a template with a data stream definition.

* Replace compile configuration usage with api (#58451)
- Use java-library instead of plugin to allow api configuration usage
- Remove explicit references to runtime configurations in dependency declarations
- Make test runtime classpath input for testing convention
- required as java library will by default not have build jar file
- jar file is now explicit input of the task and gradle will ensure its properly build
* Fix compile usages in 7.x branch
This commits allows data streams to be a valid source for analytics and transforms.
Data streams are fairly transparent and our `_search` and `_reindex` actions work without error.
For `_transforms` the check-pointing works as desired as well. Data streams are effectively treated as an `alias` and the backing index values are stored within checkpointing information.
* Remove usage of deprecated testCompile configuration
* Replace testCompile usage by testImplementation
* Make testImplementation non transitive by default (as we did for testCompile)
* Update CONTRIBUTING about using testImplementation for test dependencies
* Fail on testCompile configuration usage
rewrite config on update if either version is outdated, credentials change,
the update changes the config or deprecated settings are found. Deprecated
settings get migrated to the new format. The upgrade can be easily extended to
do any necessary re-writes.

backport #57648
The original implementation utilized `bbox` as the index mapping type. This would not work as it would have to be `envelope`. But, given that `envelope` and `polygon` are tessellated in the same way, we choose to use `polygon` as the geo_shape type. This is for easier support other places in the stack (a la kibana maps)
* [Transform] add support for terms agg in transforms (#56696)
This adds support for `terms` and `rare_terms` aggs in transforms.
The default behavior is that the results are collapsed in the following manner:
`<AGG_NAME>.<BUCKET_NAME>.<SUBAGGS...>...`
Or if no sub aggs exist
`<AGG_NAME>.<BUCKET_NAME>.<_doc_count>`
The mapping is also defined as `flattened` by default. This is to avoid field explosion while still providing (limited) search and aggregation capabilities.
This is a simple naming change PR, to fix the fact that "metadata" is a
single English word, and for too long we have not followed general
naming conventions for it. We are also not consistent about it, for
example, METADATA instead of META_DATA if we were trying to be
consistent with MetaData (although METADATA is correct when considered
in the context of "metadata"). This was a simple find and replace across
the code base, only taking a few minutes to fix this naming issue
forever.
add 2 additional stats: processing time and processing total which capture the
time spent for processing results and how often it ran. The 2 new stats
correspond to the existing indexing and search stats. Together with indexing
and search this now allows the user to see the full picture, all 3 stages.
This commit changes the Transforms notifications index to be hidden
index, with a hidden alias.
This commit also removes the temporary hack in
MetaDataCreateIndexService that prevents deprecation warnings for known
dot-prefixed index names which are not hidden/system indices, as this
was the last index pattern to need that hack.
audit messages are stored in the notifications index, so audit information is lost for integration
tests. This change forwards audit messages to logs, so they can help to debug issues.
relates: #51627
check bulk indexing error for permanent problems and ensure the state goes into failed instead of
retry. Corrects the stats API to show the real error and avoids excessive audit logging.
fixes#50122
If a transform config got lost (e.g. because the internal index disappeared) tasks could not be
stopped using transform API. This change makes it possible to stop transforms without a config,
meaning to remove the background task. In order to do so force must be set to true.
fix force stopping transform if indexer state hasn't been written and/or is set to STOPPED. In certain situations the transform could not be stopped, which means the task could not be removed. Introduces improved abstraction in order to better test state handling in future.
improve error handling for script errors, treating it as irrecoverable errors which puts the task
immediately into failed state, also improves the error extraction to properly report the script
error.
fixes#48467
rename internal indexes of transform plugin
- rename audit index and create an alias for accessing it, BWC: add an alias for old indexes to
keep them working, kibana UI will switch to use the read alias
- rename config index and provide BWC to read from old and new ones
