Add a cluster setting to disallow expensive queries (#51385) (#52279)
Add a new cluster setting `search.allow_expensive_queries` which by
default is `true`. If set to `false`, certain queries that have
usually slow performance cannot be executed and an error message
is returned.

- Queries that need to do linear scans to identify matches:
  - Script queries
- Queries that have a high up-front cost:
  - Fuzzy queries
  - Regexp queries
  - Prefix queries (without index_prefixes enabled
  - Wildcard queries
  - Range queries on text and keyword fields
- Joining queries
  - HasParent queries
  - HasChild queries
  - ParentId queries
  - Nested queries
- Queries on deprecated 6.x geo shapes (using PrefixTree implementation)
- Queries that may have a high per-document cost:
  - Script score queries
  - Percolate queries

Closes: #29050

[SPATIAL] Backport new ShapeFieldMapper and ShapeQueryBuilder to 7x (#45363)
* Introduce Spatial Plugin (#44389)

Introduce a skeleton Spatial plugin that holds new licensed features coming to 
Geo/Spatial land!

* [GEO] Refactor DeprecatedParameters in AbstractGeometryFieldMapper (#44923)

Refactor DeprecatedParameters specific to legacy geo_shape out of
AbstractGeometryFieldMapper.TypeParser#parse.

* [SPATIAL] New ShapeFieldMapper for indexing cartesian geometries (#44980)

Add a new ShapeFieldMapper to the xpack spatial module for
indexing arbitrary cartesian geometries using a new field type called shape.
The indexing approach leverages lucene's new XYShape field type which is
backed by BKD in the same manner as LatLonShape but without the WGS84
latitude longitude restrictions. The new field mapper builds on and
extends the refactoring effort in AbstractGeometryFieldMapper and accepts
shapes in either GeoJSON or WKT format (both of which support non geospatial
geometries).

Tests are provided in the ShapeFieldMapperTest class in the same manner
as GeoShapeFieldMapperTests and LegacyGeoShapeFieldMapperTests.
Documentation for how to use the new field type and what parameters are
accepted is included. The QueryBuilder for searching indexed shapes is
provided in a separate commit.

* [SPATIAL] New ShapeQueryBuilder for querying indexed cartesian geometry (#45108)

Add a new ShapeQueryBuilder to the xpack spatial module for
querying arbitrary Cartesian geometries indexed using the new shape field
type.

The query builder extends AbstractGeometryQueryBuilder and leverages the
ShapeQueryProcessor added in the previous field mapper commit.

Tests are provided in ShapeQueryTests in the same manner as
GeoShapeQueryTests and docs are updated to explain how the query works.

Adrien Grand a0af88e996 Query DSL: Remove filter parsers.
This commit makes queries and filters parsed the same way using the
QueryParser abstraction. This allowed to remove duplicate code that we had
for similar queries/filters such as `range`, `prefix` or `term`.
