* Remove usage of deprecated testCompile configuration
* Replace testCompile usage by testImplementation
* Make testImplementation non transitive by default (as we did for testCompile)
* Update CONTRIBUTING about using testImplementation for test dependencies
* Fail on testCompile configuration usage
Allow a field inside the data to be used as a tie breaker for events
that have the same timestamp.
The field is optional by default.
If used, the tie-breaker always requires a non-null value since it is
used inside `search_after` which requires a non-null value.

* Convert to date/datetime the result of numeric aggregations (min, max)
in Painless scripts
(cherry picked from commit f1de99e2a6fbf3806c4f2b6b809738aa8faa2d75)
Some BI tools (i.e. Tableau) would try to cast strings where the time
part is separated from the date part with a whitespace instead of `T`.
Adjust type conversion used by CAST to support this.

Initial support for EQL sequences
The current algorithm is focused on correctness and does not contain
any optimization which is left for the future.
The current implementation uses a state machine approach which moves
ascending and runs each query one after the other working on computing
sequences as the data comes in.
For each result, the key and its timestamp are being extracted which are
then used for matching/building a sequence.

* QL: case sensitive support in EQL (#56404)
* adds a generic startsWith function to QL
* modifies the existent EQL startsWith function to be case sensitive
aware
* improves the existent EQL startsWith function to use a prefix query
when the function is used in a case sensitive context. Same improvement
is used in SQL's newly added STARTS_WITH function.
* adds case sensitivity to EQL configuration through a case_sensitive
parameter in the eql request, as established in #54411.
The case_sensitive parameter can be specified when running queries
(default is case insensitive)

* Simplify equals/not-equals TRUE/FALSE expressions, by returning them
as is (TRUE variant) or negating them (FALSE variant)
(cherry picked from commit 17858afbe6da5fa0b3ecfc537cabb337e4baaffe)
Previously, the timezone parameter was not passed to the RangeQuery
and as a results queries that use the ES date math notation (now,
now-1d, now/d, now/h, now+2h, etc.) were using the UTC timezone and
not the one passed through the "timezone"/"time_zone" JDBC/REST params.
As a consequence, the date math defined dates were always considered in
UTC and possibly led to incorrect results for queries like:
```
SELECT * FROM t WHERE date BETWEEN now-1d/d AND now/d
```

This has no practical impact on users since frozen indices are the only
throttled indices today. However this has an impact on upcoming features
that would use search throttling.
Filtering out throttled indices made sense a couple years ago, but as
we're now improving support for slow requests with `_async_search` and
exploring ways to reduce storage costs, this feature has most likely
become a trap, that we'd like to not have with upcoming features that
would use search throttling.

* Drop BASE TABLE type in favour for just TABLE
This commit drops the table type 'BASE TABLE' and replaces all
occurences with just 'TABLE', since his type is wider-used and
friendlier to the client applications that query for certain table types
in their discovery mode.
The 'TABLE' type is also explicitely mentioned by the JDBC and ODBC
standards and although other data source-specific types are permitted,
older apps will not work well with them.
* Refactor table type constants out of IndexType
Move SQL_TABLE/_ALIAS out of IndexType, so that they can also be used in
that Enum definition.

Some functions act as shortcuts for more verbose declarations (sometimes
with certain constraints). This PR removes the boilerplate around
declaring such functions as well as a dedicated rule for the optimizer
to perform the actual substitution.
Fix#54334
(cherry picked from commit 3231d01b0c583deb89252fafe84db48878da3246)
This is a simple naming change PR, to fix the fact that "metadata" is a
single English word, and for too long we have not followed general
naming conventions for it. We are also not consistent about it, for
example, METADATA instead of META_DATA if we were trying to be
consistent with MetaData (although METADATA is correct when considered
in the context of "metadata"). This was a simple find and replace across
the code base, only taking a few minutes to fix this naming issue
forever.
* EQL: Use In from QL
* EQL: Add more In tests
* EQL: Test In duplicates
* EQL: Add test for In mixed types
* EQL: Copy In translation to QL
* SQL: Use InComparisons from QL
* EQL: Remove boost checks from QueryFolderOkTests
* QL: Add TranslatorHandler.convert
Improve separation of scripting between EQL and SQL by delegating common
methods to QL. The context detection is determined based on the package
to avoid having repetitive class hierarchies.
The Painless whitelists have been improved so that the declaring class
is used instead of the inherited one.

EQL: Add Substring function with Python semantics (#53688)
Does not reuse substring from SQL due to the difference in semantics and
the accepted arguments.
Currently it is missing full integration tests as, due to the usage of
scripting, requires an actual integration test against a proper cluster
(and likely its own QA project).

Add missing asScript() implementation for LIKE/RLIKE expressions.
When LIKE/RLIKE are used for example in GROUP BY or are wrapped with
scalar functions in a WHERE clause, the translation must produce a
painless script which will be executed to implement the correct
behaviour and previously this was completely missing, and as a
consquence wrong results were silently (no error) returned.

This commit makes the names of fetch subphases more consistent:
* Now the names end in just 'Phase', whereas before some ended in
'FetchSubPhase'. This matches the query subphases like AggregationPhase.
* Some names include 'fetch' like FetchScorePhase to avoid ambiguity about what
they do.

This fixes:
- the parsing of milliseconds in intervals: everything past the . used to be converted as-is to milliseconds, with no normalisation of the unit; thus, a value of .23 ended up as 23 millis in the interval, instead of 230.
- the printing of a trailing .0, in case the interval lacks the fractional part;
- tests generating a random millisecond value used to simply print it in the string about to be evaluated without a necessary front-filling of 0[s], where the amount was below 100/10.
(The combination of first and last issues above, plus statistical "luck" made the incorrect handling pass the tests.)
