Currently, if you write a date range query with numeric 'to' or 'from' bounds,
they can be interpreted as years if no format is provided. We use
"strict_date_optional_time||epoch_millis" in this case that can interpret inputs
like 1000 as the year 1000 for example.
This PR change this to always interpret and parse numbers with the "epoch_millis"
parser if no other formatter was provided.
Closes#63680
Setting a slow log level requires an unnecessary conditional logic in SearchSlowLog and IndexingSlowLog
The behaviour of setting a level on a slow logger can be achieved with correct slow log threshold settings.
This PR is removing slow log and modifies tests to achieve the same behaviour with changing threshold.
relates #56171
Tries to load a `Mapper` instance for the mapping snippet of a dynamic template.
This should catch things like using an analyzer that is undefined or mapping attributes that are unused.
This is best effort:
* If `{{name}}` placeholder is used in the mapping snippet then validation is skipped.
* If `match_mapping_type` is not specified then validation is performed for all mapping types.
If parsing succeeds with a single mapping type then this the dynamic mapping is considered valid.
If is detected that a dynamic template mapping snippet is invalid at mapping update time then the mapping update is failed for indices created on 8.0.0-alpha1 and later. For indices created on prior version a deprecation warning is omitted instead. In 7.x clusters the mapping update will never fail in case of an invalid dynamic template mapping snippet and a deprecation warning will always be omitted.
