35fe05308e SQL: rewrite ROUND and TRUNCATE functions with a different optional parameter handling method (#40242)
* Rewrite Round and Truncate functions to have a slightly different
approach to handling the optional parameter in the constructor. Until now
the optional parameter was considered 0 if the value was missing and the
constructor was filling in this value. The current solution is to have
the optional parameter as null right until the actual calculation is done.

SQL: Fix issue with optimization on queries with ORDER BY/LIMIT (#40256)
Previously, when a trival plain `SELECT` or a trivial `SELECT` with
aggregations has also an `ORDER BY` or a `LIMIT` or both, then the
optimization to convert it to a `LocalRelation` was skipped resulting
in exception thrown. E.g.::
```
SELECT 'foo' FROM test LIMIT 10
```
or
```
SELECT 'foo' FROM test GROUP BY 1 ORDER BY 1
```

bc4c8e53c5 SQL: Fix issue with date columns returned always in UTC (#40163)
When selecting columns of ES type `date` (SQL's DATETIME) the
`FieldHitExtractor` was not using the timezone of the client session
but always resorted to UTC. The same behaviour (UTC only) was
encountered also for grouping keys (`CompositeKeyExtractor`) and
for First/Last functions on dates (`TopHitsAggExtractor`).

For cases where fields can have multi values, allow the behavior to be
customized through a dedicated configuration field.
By default this will be enabled on the drivers so that existing datasets
work instead of throwing an exception.
For regular SQL usage, the behavior is false so that the user is aware
of the underlying data.

4e9657f93f SQL: Fix bug with JDBC timezone setting and DATE type (#39978)
Previously, JDBC's REST call to the server was always sending UTC
instead of the timezone passed through connection string/properties.

Moreover the conversion to java.sql.Date was problematic as a
calculation on the epoch millis was used to set the time to 00:00:00.000
and the timezone info was lost. This caused the resulting java.sql.Date
object which is always using the JVM's timezone (no matter what timezone
setting is used in the connection string/properties) to be wrongly created.

Bundle java in distributions (#38013)
* Bundle java in distributions

Setting up a jdk is currently a required external step when installing
elasticsearch. This is particularly problematic for the rpm/deb packages
as installing a jdk in the same package installation command does not
guarantee any order, so must be done in separate steps. Additionally,
JAVA_HOME must be set and often causes problems in selecting a correct
jdk when, for example, the system java is an older unsupported version.

This commit bundles platform specific openjdks into each distribution.
In addition to eliminating the issues above, it also presents future
possible improvements like using jlink to build jdk images only
containing modules that elasticsearch uses.

SQL: Fix esType for DATETIME/DATE and INTERVALS (#38179)

in ES the `esType` is error-prone when used for `unmappedType()` calls.

is not a valid type for ES mapping.

Make sure to reject mappings with type _doc when include_type_name is false. (#38270)
`CreateIndexRequest#source(Map<String, Object>, ... )`, which is used when
deserializing index creation requests, accidentally accepts mappings that are
nested twice under the type key (as described in the bug report #38266).

This in turn causes us to be too lenient in parsing typeless mappings. In
particular, we accept the following index creation request, even though it
should not contain the type key `_doc`:

```
PUT index?include_type_name=false
{
  "mappings": {
    "_doc": {
      "properties": { ... }
    }
  }
}
```

There is a similar issue for both 'put templates' and 'put mappings' requests
as well.

This PR makes the minimal changes to detect and reject these typed mappings in
requests. It does not address #38266 generally, or attempt a larger refactor
around types in these server-side requests, as I think this should be done at a
later time.
