* Wrap a verification_exception in case there is no valid index available (#64267)
Wrap a verification_exception in case there is no valid index available in an index_not_found_exception providing also the original index pattern that may be lost in the chain of filters involving the Security one.

Costin Leau 2ab5f226c4 EQL: Avoid filtering on tiebreakers (#63415)
Do not filter by tiebreaker while searching sequence matches as
it's not monotonic and thus can filter out valid data.
Add handling for data 'near' the boundary that has the same timestamp
but different tie-breaker and thus can be just outside the window.

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.

Costin Leau 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.

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).

Costin Leau 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.

Sequences now support until conditional, which prevents a match from

Thus a sequence must complete before the until condition matches - if
any document within the sequence occurs at, or after, the until hit, the
sequence is discarded.

Costin Leau f9c15d0fec EQL: Introduce sequencing fetch size (#59063)
The current internal sequence algorithm relies on fetching multiple results and then paginating through the dataset. Depending on the dataset and memory, setting a larger page size can yield better performance at the expense of memory.
This PR makes this behavior explicit by decoupling the fetch size from size, the maximum number of results desired.
As such, use in testing a minimum fetch size which exposed a number of bugs:

Jumping across data across queries causing valid data to be seen as a gap.
Incorrectly resuming searching across pages (again causing data to be discarded).
which have been addressed.

Costin Leau 9f1ecd52eb EQL: Introduce support for sequences (#56300)
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.
