Today when parsing settings during bootstrap, we add a system property
for every Elasticsearch setting. Additionally, settings can be set via
system properties. This commit simplifies this situation.
- settings are no longer propogated to system properties
- system properties can not be used to set settings
- the "es." prefix on settings is no longer required (nor permitted)
- test logging has a dedicated system property (tests.logger.level)

* Docs: Improved tokenizer docs
Added descriptions and runnable examples
* Addressed Nik's comments
* Added TESTRESPONSEs for all tokenizer examples
* Added TESTRESPONSEs for all analyzer examples too
* Added docs, examples, and TESTRESPONSES for character filters
* Skipping two tests:
One interprets "$1" as a stack variable - same problem exists with the REST tests
The other because the "took" value is always different
* Fixed tests with "took"
* Fixed failing tests and removed preserve_original from fingerprint analyzer
The preserve_original option to the ASCIIFoldingFilter doesn't
play well with the FingerprintFilter, as it ends up producing
fingerprints like:
"and consistent godel gödel is said sentence this yes"
The goal of the OpenRefine algorithm is to product a small normalized
ASCII fingerprint. There's no need to expose preserve_original.
We often require a random joda DateTimeZone in our tests. Currently
there are a few options for generating such a random DateTimeZone
from the set of available ids. Currently most random picks are not
really reproducable across different jvms because they rely on order
in the ids set implementation. The helper in DateProcessorFactoryTests
thus performs a sort on the set of ids before random picking from
the result, so I moved this to ESTestCase to make it publicly
available and changed all other tests to use that method.
From 2.0 adding child types to existing types was forbidden because the`_parent` field stores the join between parent and child at index time.
This is to protect from the fact that types that weren't a parent before become a parent while previously indexed documents would not have a join field.
This would break the parent/child queries.
The restriction was a bit too strict in the sense that also if a type was a parent type the restriction would forbid adding child types that point to a parent type (so child points already point to it).
This change make sure that the restriction only applies if that type isn't a parent type already.

* Register `indices.query.bool.max_clause_count` setting
This commit registers `indices.query.bool.max_clause_count` as a node
level setting and removes support for its synonym setting
`index.query.bool.max_clause_count`.

FSync translog outside of the writers global lock
Today we aquire a write global lock that blocks all modification to the
translog file while we fsync / checkpoint the file. Yet, we don't necessarily
needt to block concurrent operations here. This can lead to a lot of blocked
threads if the machine has high concurrency (lot os CPUs) but uses slow disks
(spinning disks) which is absolutely unnecessary. We just need to protect from
fsyncing / checkpointing concurrently but we can fill buffers and write to the
underlying file in a concurrent fashion.
This change introduces an additional lock that we hold while fsyncing but moves
the checkpointing code outside of the writers global lock.
This commit fixes the inequality symbol used in a test assertion in
RepositoryS3SettingsTests#testInvalidChunkBufferSizeRepositorySettings. The
inequality symbol was previously backwards but fixed in commit
cad0608cdb28e2b8485e5c01c26579a35cb84356 but fixing the inequality
symbol here was missed in that commit.
Closes#18449
Currently rounding intervals obtained by nextRoundingValue() for hour, minute and
second units can include an extra hour when happening at DST transitions that add
an extra hour (eg CEST -> CET). This changes the rounding logic for time units
smaller or equal to an hour to fix this.
Closes#18326
This commit adds simple GC overhead logging. This logging captures
intervals where the JVM is spending a lot of time performing GC but it
is not necessarily the case that each GC is large. For a start, this
logging is simple and does not attempt to incorporate whether or not the
collections were efficient (that is, we are only capturing that a lot of
GC is happening, not that a lot of useless GC is happening).

We are currently only parsing the array-syntax for the rescore part
in SearchSourceBuilder ("rescore" : [ {...}, {...} ]) . We also need
to support "rescore" : {...}
Closes#18439
