Currently, CAST will use the first keyword subfield of a text field for
an expression in WHERE clause that gets translated to a painless script
which will lead to an exception thrown:
```
"root_cause": [
{
"type": "script_exception",
"reason": "runtime error",
"script_stack": [
"org.elasticsearch.index.mapper.TextFieldMapper$TextFieldType.fielddataBuilder(TextFieldMapper.java:759)",
"org.elasticsearch.index.fielddata.IndexFieldDataService.getForField(IndexFieldDataService.java:116)",
"org.elasticsearch.index.query.QueryShardContext.lambda$lookup$0(QueryShardContext.java:308)",
"org.elasticsearch.search.lookup.LeafDocLookup$1.run(LeafDocLookup.java:101)",
"org.elasticsearch.search.lookup.LeafDocLookup$1.run(LeafDocLookup.java:98)",
"java.security.AccessController.doPrivileged(Native Method)",
"org.elasticsearch.search.lookup.LeafDocLookup.get(LeafDocLookup.java:98)",
"org.elasticsearch.search.lookup.LeafDocLookup.get(LeafDocLookup.java:41)",
"org.elasticsearch.xpack.sql.expression.function.scalar.whitelist.InternalSqlScriptUtils.docValue(InternalSqlScriptUtils.java:79)",
"InternalSqlScriptUtils.cast(InternalSqlScriptUtils.docValue(doc,params.v0),params.v1)",
" ^---- HERE"
],
"script": "InternalSqlScriptUtils.cast(InternalSqlScriptUtils.docValue(doc,params.v0),params.v1)",
"lang": "painless"
}
],
```
Instead of allowing a painless translation using the first underlying
keyword silently, which can be confusing, we detect such usage and throw\
an error early.

Bwc tests can consume much time to build and to run so it's nice to be
able to skip them when running the `check` task on the SQL module.
Introduce a new task `checkNoBwc` so one can use:
```
./gradlew -p x-pack/plugin/sql checkNoBwc
```
to skip them.

Eclipse was confused for two reasons:
1. `:x-pack:plugin` depended on itself.
2. `ql`, `sql`, and `eql` couldn't see some methods.
I fixed problem 1 by only adding the "depends on itself" configuration
outside of eclipse. I fixed problem 2 by making a `test` sub-project in
`ql` that contains test utilities and depending on those where possible.

This new snapshot contains the following JIRAs that we're interested in:
- [LUCENE-9525](https://issues.apache.org/jira/browse/LUCENE-9525)
Better handling of small documents. This should improve retrieval times
when documents are less than ~1kB.
- [LUCENE-9510](https://issues.apache.org/jira/browse/LUCENE-9510)
Faster flushes when index sorting is enabled by not compressing the
temporary files that store stored fields and term vectors.
Prevent the analyzer for trying to resolve aliases on expressions that
reference themselves (or fields within themselves) as that causes
infinite recursion.

This commit removes `integTest` task from all es-plugins.
Most relevant projects have been converted to use yamlRestTest, javaRestTest,
or internalClusterTest in prior PRs.
A few projects needed to be adjusted to allow complete removal of this task
* x-pack/plugin - converted to use yamlRestTest and javaRestTest
* plugins/repository-hdfs - kept the integTest task, but use `rest-test` plugin to define the task
* qa/die-with-dignity - convert to javaRestTest
* x-pack/qa/security-example-spi-extension - convert to javaRestTest
* multiple projects - remove the integTest.enabled = false (yay!)

This commit does three things:
* Removes all Copyright/license headers for the build.gradle files under x-pack. (implicit Apache license)
* Removes evaluationDependsOn(xpackModule('core')) from build.gradle files under x-pack
* Removes a place holder test in favor of disabling the test task (in the async plugin)
- Replace immediate task creations by using task avoidance api
- One step closer to #56610
- Still many tasks are created during configuration phase. Tackled in separate steps
* SQL: Add option to provide the delimiter for the CSV format (#59907)
* Add option to provide the delimiter to the CSV fmt
This adds the option to provide the desired character as the separator
for the CSV format (the default remains comma).
A set of characters are excluded though - like CR, LF, `"` - to avoid
slipping onto the CSV-dialects slope. The tab is also forbidden, the
user needs to choose the "tsv" format explicitely.
Update the doc to make it clear that the textual CSV, TSV and TXT
formats pass the cursor back to the user through the Cursor HTTP header.

(cherry picked from commit 9ba70a3483f0f4987229bec231cdc004f51b88a5)
This commit adds compatibility testing of our JDBC driver against
different Elasticsearch versions. Although we are really testing the
forwards compatibility nature of the JDBC driver we model the testing
the same as we do existing BWC tests, that is, with the current branch
fetching the earlier versions of the artifact that is to be tested. In
this case, that's the JDBC driver itself.
Because the tests include the JDBC driver jar on it's classpath we had
to change the packaging of the driver jar in order to avoid jarhell and
other conflicting dependency issues when using an old JDBC driver with
later branches. For this we simply relocate all driver dependencies in
the shadow jar under a "shadowed" package. This allows the JDBC driver
to use the correct version of Elasticsearch libs classes, while the
tests themselves use their versions. Since this required a change to the
driver jar compatibility testing can only go back as far as that version
which at the time of this commit is 7.8.1.
This feature adds a new `fields` parameter to the search request, which
consults both the document `_source` and the mappings to fetch fields in a
consistent way. The PR merges the `field-retrieval` feature branch.
Addresses #49028 and #55363.
Implement DATE_PARSE(<date_str>, <pattern_str>) function
which allows to parse a date string according to the specified
pattern into a date object. The patterns allowed are those of
java.time.format.DateTimeFormatter.

* SQL: Redact credentials in connection exceptions (#58650)
This commit adds the functionality to redact the credentials from the
exceptions generated when a connection attempt fails, preventing them
from leaking into logs, console history etc.
There are a few causes that can lead to failed connections. The most
challenging to deal with is a malformed connection string. The redaction
tries to get around it by modifying the URI to a parsable state, so that
the redaction can be applied reliably. If there's no reliability
guarantee, the redaction will bluntly replace the entire connection
string and the user informed about the option to modify it so that the
redaction won't apply. (This is done by using a caplitalized scheme,
which is legal, but otherwise never used in practice.)
The commit fixes a couple of other issues with the URI parser:
- it allows an empty hostname, or even entire connection string (as per
the existing documentation);
- it reduces the editing of the connection string in the exception
messages (so that the user easier recognize their input);
- it uses the default URI as source for the scheme and hostname.

SQL: fix handling of escaped chars in JDBC connection string (#58429)
This commit fixes an issue emerging when the connection string URI
contains escaped characters.
The original URI is pre-parsed in order to re-assemble a new URI having
the optional elements filled in with defaults. The new URI has been
using however the unescaped query and fragment parts. So if these
contained any escaped `&` or `=` (such as in the password option value),
the unescaping would reveal them and make them later interfere with the
options parsing.
The commit changes that, so that the new URI be built from the unescaped
"raw" parts of the original URI.

The checks on the license state have a singular method, isAllowed, that
returns whether the given feature is allowed by the current license.
However, there are two classes of usages, one which intends to actually
use a feature, and another that intends to return in telemetry whether
the feature is allowed. When feature usage tracking is added, the latter
case should not count as a "usage", so this commit reworks the calls to
isAllowed into 2 methods, checkFeature, which will (eventually) both
check whether a feature is allowed, and keep track of the last usage
time, and isAllowed, which simply determines whether the feature is
allowed.
Note that I considered having a boolean flag on the current method, but
wanted the additional clarity that a different method name provides,
versus a boolean flag which is more easily copied without realizing what
the flag means since it is nameless in call sites.
* Replace compile configuration usage with api (#58451)
- Use java-library instead of plugin to allow api configuration usage
- Remove explicit references to runtime configurations in dependency declarations
- Make test runtime classpath input for testing convention

- jar file is now explicit input of the task and gradle will ensure its properly build
* Fix compile usages in 7.x branch
RandomZone test method returns a ZoneId from the set of ids supported by
java. The only difference between joda and java supported timezones are
SystemV* timezones.
These should be excluded from randomZone method as they would break
testing. They also do not bring much confidence when used in testing as
I suspect they are rarely used.
That exclude should be removed for simplification once joda support is removed.
Introduce pipe support, in particular head and tail
(which can also be chained).

If a project is pulling in an external org.elasticsearch dependency, the dependency

This would break precommit because a license was present that it did not feel was

JNA license addition.
