To be consistent with the `search.max_buckets` default setting,
set the hard limit of the PriorityQueue used for in memory sorting,
when sorting on an aggregate function, to 10000.

- Previously, when shorting on an aggregate function the bucket
processing ended early when the explicit (LIMIT XXX) or the impliciti
limit of 512 was reached. As a consequence, only a set of grouping
buckets was processed and the results returned didn't reflect the global
ordering.
- Previously, the priority queue shorting method had an inverse
comparison check and the final response from the priority queue was also
returned in the inversed order because of the calls to the `pop()`
method.

The description field of xpack featuresets is optionally part of the
xpack info api, when using the verbose flag. However, this information
is unnecessary, as it is better left for documentation (and the existing
descriptions describe anything meaningful). This commit removes the
description field from feature sets.
* Take into consideration a wider range of Numbers when extracting the

In AsciiDoc, `subs="attributes,callouts,macros"` options were required
to render `include-tagged::` in a code block.
With elastic/docs#827, Elasticsearch Reference documentation migrated
from AsciiDoc to Asciidoctor.
In Asciidoctor, the `subs="attributes,callouts,macros"` options are no
longer needed to render `include-tagged::` in a code block. This commit
removes those unneeded options.

Due to a bug in JTS WKT parser, JTS cannot parse most of WKT shapes if
the shape type is written in the lower case. For examples `point (1 2)`
is causing JTS inside H2GIS to fail on tr-TR locale as a result of
case-insensitive comparison.
Interval * integer number is a valid operation which previously was
only supported for foldables (literals) and not when a field was
involved. That was because:
1. There was no common type returned for that combination
2. The `BinaryArithmeticOperation` was permitting the multiplication
(called by fold()) but the BinaryArithmeticProcessor didn't allow it
Moreover the error message for invalid arithmetic operations was wrong
because of the issue with the overloading methods of
`LoggerMessageFormat.format`.

Adds an initial limited implementations of geo features to SQL. This implementation is based on the [OpenGIS® Implementation Standard for Geographic information - Simple feature access](http://www.opengeospatial.org/standards/sfs), which is the current standard for GIS system implementation. This effort is concentrate on SQL option AKA ISO 19125-2.
Queries that are supported as a result of this initial implementation
Metadata commands
- `DESCRIBE table` - returns the correct column types `GEOMETRY` for geo shapes and geo points.
- `SHOW FUNCTIONS` - returns a list that includes supported `ST_` functions
- `SYS TYPES` and `SYS COLUMNS` display correct types `GEO_SHAPE` and `GEO_POINT` for geo shapes and geo points accordingly.
Returning geoshapes and geopoints from elasticsearch
- `SELECT geom FROM table` - returns the geoshapes and geo_points as libs/geo objects in JDBC or as WKT strings in console.
- `SELECT ST_AsWKT(geom) FROM table;` and `SELECT ST_AsText(geom) FROM table;`- returns the geoshapes ang geopoints in their WKT representation;
Using geopoints to elasticsearch
- The following functions will be supported for geopoints in queries, sorting and aggregations: `ST_GeomFromText`, `ST_X`, `ST_Y`, `ST_Z`, `ST_GeometryType`, and `ST_Distance`. In most cases when used in queries, sorting and aggregations, these function are translated into script. These functions can be used in the SELECT clause for both geopoints and geoshapes.
- `SELECT * FROM table WHERE ST_Distance(ST_GeomFromText(POINT(1 2), point) < 10;` - returns all records for which `point` is located within 10m from the `POINT(1 2)`. In this case the WHERE clause is translated into a range query.
Limitations:
Geoshapes cannot be used in queries, sorting and aggregations as part of this initial effort. In order to fully take advantage of geoshapes we would need to have access to geoshape doc values, which is coming in #37206. `ST_Z` cannot be used on geopoints in queries, sorting and aggregations since we don't store altitude in geo_point doc values.

Backport of #42031
The CircuitBreaker was introduced as means of preventing a
`StackOverflowException` during the build of the AST by the parser.
The ANTLR4 grammar causes a weird behaviour for a Parser Listener.
The `enterEveryRule()` method is often called with a different parsing
context than the respective `exitEveryRule()`. This makes it difficult
to keep track of the tree's depth, and a custom Map was used as an
attempt of matching the contextes as they are encounter during `enter`
and during `exit` of the rules.
This approach had 2 important drawbacks:
1. It's hard to maintain this custom Map as the grammar changes.
2. The CircuitBreaker could often lead to false positives which caused
valid queries to return an Exception and prevent them from executing.
So, this removes completely the CircuitBreaker which is replaced be
a simple handling of the `StackOverflowException`

The SimplifyConditional rule is removing NULL literals from those
functions to simplify their evaluation. This happens in the Optimizer
and a new instance of the conditional function is generated. Previously,
the dataType was not set properly (defaulted to DataType.NULL) for
those new instances and since the resolveType() wasn't called again
it resulted in returning always null.
E.g.:
SELECT COALESCE(null, 'foo', null, 'bar')
COALESCE(null, 'foo', null, 'bar')
-----------------
null
This issue was not visible before because the tests always used an alias
for the conditional function which caused the resolveType() to be
called which sets the dataType properly.
E.g.:
SELECT COALESCE(null, 'foo', null, 'bar') as c
c
-----------------
foo

CURRENT_DATE/CURRENT_TIME/CURRENT_TIMESTAMP can be used as SQL keywords
(without parentheses) and therefore there is a special rule in the
grammar to accommodate this.
Previously, this rule was also catching the parenthesised version of those functions too,
not allowing the {fn <functionName>()} to be used. E.g.:
{fn current_time(2)} or {fn current_timestamp()}
Now, the grammar rule catches only the keyword versions and all the parenthesised
versions go through the normal function resolution. As a consequence the validation
of the precision is moved from the parser lever (ExpressionBuilder) to the function
implementations.
