EQL: [Tests] Adjust README for preserving test data (#65460)
Adjusted the README file to mention both the option to preserve the test
data when simple reproducing/executing the tests, but also when starting
the server node manually and issuing the query(ies) against it.

f089547b20 EQL: Fix aggressive/incorrect until policy in sequences (#65156)
The current until implementation in sequences is too optimistic, leading
to an aggressive match that discards correct data leading to invalid
results.
This commit addresses this issue and also unifies the until usage inside
TumblingWindow.
Further more it packs together the UntilGroup with SequenceGroup to
minimize memory usage and improve clean-up.

EQL: Add option for returning results from the tail of the stream (#64869) (#65040)
Introduce option for specifying whether the results are returned from
the tail (end) of the stream or the head (beginning).
Improve sequencing algorithm by significantly eliminating the number
of in-flight sequences for spare datasets.
Refactor the sequence class by eliminating some of the redundant code.
Change matching behavior for tail sequences.
Return results based on their first entry ordinal instead of
insertion order (which was ordered on the last match ordinal).
Randomize results position inside test suite.

EQL: Replace ?"..." with """...""" for unescaped strings (#62539) (#63174)
Use triple double quotes enclosing a string literal to interpret it
as unescaped, in order to use `?` for marking query params and avoid
user confusion. `?` also usually implies regex expressions.

Any character inside the `"""` beginning-closing markings is considered
raw and the only thing that is not permitted is the `"""` sequence itself.
If a user wants to use that, needs to resort to the normal `"` string literal
and use proper escaping.

c2992ea287 EQL: Fix NPE from incorrect use of ids search (#63032)
This fixes a bug introduced when moving from mget to ids query. While
mget returns all the ids given, id query is a search query and thus by
default returns only 10 documents.
The fix correctly sets the expected size so all the information is
returned inside the response.

Fix Eclipse build (#62733) (#62786)
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.

Fix data stream wildcard resolution bug in eql search api.(#61910)
Backport of #61904 to 7.x branch.

The eql search api redirects to the search api. For this reason the eql
search api could work with concrete data stream names. However if security
is enabled and a data stream name snippet with a wildcard was used then
it could not resolve this expressions. This is because the EqlSearchRequest
class didn't overwrite the `includeDataStreams()` method. This pr fixes this,
so that the security layer can properly expand data stream name wildcard
expressions for the eql search api.

This commit also moves the eql data stream test to xpack rest tests,
so that the test runs with security enabled. This is required to reproduce
the bug.

[7.x] Convert first 1/2 x-pack plugins from integTest to [yaml | java]RestTest or internalClusterTest (#60630) (#61855)
For 1/2 the plugins in x-pack, the integTest
task is now a no-op and all of the tests are now executed via a test,
yamlRestTest, javaRestTest, or internalClusterTest.

This includes the following projects:
async-search, autoscaling, ccr, enrich, eql, frozen-indicies,
data-streams, graph, ilm, mapper-constant-keyword, mapper-flattened, ml

A few of the more specialized qa projects within these plugins
have not been changed with this PR due to additional complexity which should
be addressed separately.

A follow up PR will address the remaining x-pack plugins (this PR is big enough as-is).

EQL: Replace SearchHit in response with Event (#61428) (#61522)
The building block of the eql response is currently the SearchHit. This
is a problem since it is tied to an actual search, and thus has scoring,
highlighting, shard information and a lot of other things that are not
relevant for EQL.
This becomes a problem when doing sequence queries since the response is
not generated from one search query and thus there are no SearchHits to
speak of.
Emulating one is not just conceptually incorrect but also problematic
since most of the data is missed or made-up.

As such this PR introduces a simple class, Event, that maps nicely to
the terminology while hiding the ES internals (the use of SearchHit or
GetResult/GetResponse depending on the API used).

9cc80621c3 EQL: Fix matching of tail/desc queries (#59827)
When dealing with tail queries, data is returned descending for the base
criterion yet the rest of the queries are ascending. This caused a
problem during insertion since while in a page, the data is ASC, between
pages the blocks of data is DESC.
This caused incorrectly sorting inside a SequenceGroup which led to
incorrect results.

Further more in case of limit, since the data in a page is ASC, early
return is not possible neither is desc matching. Thus the page needs to
be consumed first before finding the final results.
A future improvement could be to keep only the top N results dropping
the rest during insertion time.
