This commit splits cluster state update tasks into roles. Those roles
are:
- task info
- task configuration
- task executor
- task listener
All tasks that have the same executor will be executed in batches. This
removes the need for local batching as was previously in
MetaDataMappingService.
Additionally, this commit reintroduces batching on mapping update calls.

When reading, through #getFieldValue and #hasField, and a list is encountered, the next element in the path is treated as the index of the item that the path points to (e.g. `list.0.key`). If the index is not a number or out of bounds, an exception gets thrown.
Added #appendFieldValue method that has the same behaviour as setFieldValue, but when a list is the last element in the path, instead of replacing the whole list it will simply add a new element to the existing list. This method is currently unused, we have to decide whether the set processor or a new processor should use it.
A few other changes made:
- Renamed hasFieldValue to hasField, as this method is not really about values but only keys. It will return true if a key is there but its value is null, while it returns false only when a field is not there at all.
- Changed null semantic in getFieldValue. null gets returned only when it was an actual value in the source, an exception is thrown otherwise when trying to access a non existing field, so that null != field not present.
- Made remove stricter about non existing fields. Throws error when trying to remove a non existing field. This is more consistent with the other methods in IngestDocument which are strict about fields that are not present.
Relates to #14324
Do not to load fields from _source when using the `fields` option.
Non stored (non existing) fields are ignored by the fields visitor when using the `fields` option.
Fixes#10783
Support * wildcard to retrieve stored fields when using the `fields` option.
Supported pattern styles are "xxx*", "*xxx", "*xxx*" and "xxx*yyy".
Its enough to test the content type for what we are testing.
Currently tests are flaky if charset is detected as e.g. windows-1252 vs iso-8859-1 and so on.
In fact, they fail on windows 100% of the time.
We are not trying to test charset detection heuristics (which might be different even due to newlines in tests or other things).
If we want to do test that, we should test it separately.
The current delay waits until later after normal configuration, but
still just after resolution (ie when paths would be known for
dependencies but not actual execution). This delays the checks further
to be done right before we actually execute the copy task.
closes#15068
Currently if running with --info, the command line for ES, along with
env vars, are logged before they may be ammended to add debug options.
This moves the adding JAVA_OPTS to before we print the command.
