Make Geo Context Mapping Parsing More Strict (#32821)
Currently, if geo context is represented by something other than
geo_point or an object with lat and lon fields, the parsing of it
as a geo context can result in ignoring the context altogether,
returning confusing errors such as number_format_exception or trying
to parse the number specifying as long-encoded hash code. It would also
fail if the geo_point was stored.

This commit makes the mapping parsing more strict and will fail during
mapping update or index creation if the geo context doesn't point to
a geo_point field.

Supersedes #32412

Closes #32202

JeffSaxeVA efdad7d5fc [DOCS] Add "remove a tag" script logic as an example (#32556)
It took me quite a while of online searching and experimenting to realize the function-call asymmetry in the Add versus Remove from a list, like the "tags" list! I realize we cannot give examples for every single thing the user wants to do in Painless, but this is such a common use case (removing a tag from a single doc, or from a set of docs with Update-By-Query) that I believe it ought to be demonstrated immediately after the "add a tag" example. We have an example of removing an entire document field, but not removing one element of a list (a multi-valued field).

Also, a minor grammar fix: I have added an apostrophe to the word "its" in the accompanying text of the example just above.

Fix docs for fixed filename for heap dump path (#32882)
The docs here incorrectly state that it is okay for a heap dump file to
exist when heap dump path is configured to a fixed filename. This is
incorrect, the JVM will fail to write the heap dump if a heap dump file
already exists at the specified location (see the DumpWriter constructor
DumpWriter::DumpWriter(const char* path) in the JVM source).

serialize suggestion responses as named writeables (#30284)
Suggestion responses were previously serialized as streamables which
made writing suggesters in plugins with custom suggestion response types
impossible. This commit makes them serialized as named writeables and
provides a facility for registering a reader for suggestion responses
when registering a suggester.

This also makes Suggestion responses abstract, requiring a suggester
implementation to provide its own types. Suggesters which do not need
anything additional to what is defined in Suggest.Suggestion should
provide a minimal subclass.

The existing plugin suggester integration tests are removed and
replaced with an equivalent implementation as an example
plugin.

Add temporary directory cleanup workarounds (#32615)
On some Linux distributions tmpfiles.d cleans files and
directories under /tmp if they haven't been accessed for
10 days.

This can cause problems for ML as ML is currently the only
component that uses the temp directory more than a few
seconds after startup. If you didn't open an ML job for
10 days and then tried to open one then the temp directory
would have been deleted.

This commit prevents the problem occurring in the case of
Elasticsearch being managed by systemd, as systemd private
temp directories are not subject to periodic cleanup (by
default).

Additionally there are now some docs to warn people about
the risk and suggest a manual mitigation for .tar.gz users.

Scripting: Conditionally use java time api in scripting (#31441)
This commit adds a boolean system property, `es.scripting.use_java_time`,
which controls the concrete return type used by doc values within
scripts. The return type of accessing doc values for a date field is
changed to Object, essentially duck typing the type to allow
co-existence during the transition from joda time to java time.

Logging: Make node name consistent in logger (#31588)
First, some background: we have 15 different methods to get a logger in
Elasticsearch but they can be broken down into three broad categories
based on what information is provided when building the logger.

Just a class like:
```
private static final Logger logger = ESLoggerFactory.getLogger(ActionModule.class);
```
or:
```
protected final Logger logger = Loggers.getLogger(getClass());
```

The class and settings:
```
this.logger = Loggers.getLogger(getClass(), settings);
```

Or more information like:
```
Loggers.getLogger("index.store.deletes", settings, shardId)
```

The goal of the "class and settings" variant is to attach the node name
to the logger. Because we don't always have the settings available, we
often use the "just a class" variant and get loggers without node names
attached. There isn't any real consistency here. Some loggers get the
node name because it is convenient and some do not.

This change makes the node name available to all loggers all the time.
Almost. There are some caveats are testing that I'll get to. But in
*production* code the node name is node available to all loggers. This
means we can stop using the "class and settings" variants to fetch
loggers which was the real goal here, but a pleasant side effect is that
the ndoe name is now consitent on every log line and optional by editing
the logging pattern. This is all powered by setting the node name
statically on a logging formatter very early in initialization.

Now to tests: tests can't set the node name statically because
subclasses of `ESIntegTestCase` run many nodes in the same jvm, even in
the same class loader. Also, lots of tests don't run with a real node so
they don't *have* a node name at all. To support multiple nodes in the
same JVM tests suss out the node name from the thread name which works
surprisingly well and easy to test in a nice way. For those threads
that are not part of an `ESIntegTestCase` node we stick whatever useful
information we can get form the thread name in the place of the node
name. This allows us to keep the logger format consistent.

update rollover to leverage write-alias semantics (#32216)
Rollover should not swap aliases when `is_write_index` is set to `true`.
Instead, both the new and old indices should have the rollover alias,
with the newly created index as the new write index

Updates Rollover to leverage the ability to preserve aliases and swap which is the write index.

Historically, Rollover would swap which index had the designated alias for writing documents against. This required users to keep a separate read-alias that enabled reading against both rolled over and newly created indices, whiles the write-alias was being re-assigned at every rollover.

With the ability for aliases to designate a write index, Rollover can be a bit more flexible with its use of aliases.

Updates include:

- Rollover validates that the target alias has a write index (the index that is being rolled over). This means that the restriction that aliases only point to one index is no longer necessary.
- Rollover explicitly (and atomically) swaps which index is the write-index by explicitly assigning the existing index to have `is_write_index: false` and have the newly created index have its rollover alias as `is_write_index: true`. This is only done when `is_write_index: true` on the write index. Default behavior of removing the alias from the rolled over index stays when `is_write_index` is not explicitly set

Relevant things that are staying the same:

- Rollover is rejected if there exist any templates that match the newly-created index and configure the rollover-alias
   - I think this existed to prevent the situation where an alias pointed to two indices for a short while. Although this can technically be relaxed, the specific cases that are safe are really particular and difficult to reason, so leaving the broad restriction sounds good

w-bonelli 072c0be8af Update Fuzzy Query docs to clarify default behavior re max_expansions (#30819)

Fix ordering of bootstrap checks in docs (#32417)
In the section of the bootstrap checks docs for the maximum map count
check, we refer to max size virtual memory check and explicitly call out
the maximum size virtual memory check as being the previous
point. However, this is not correct as the previous point is currently
the max file size check. It does make sense for these two checks to be
proximate to each other in the docs so this commit reorders the checks
so that the maximum size virtual memory check indeed comes before the
maximum map count check. This makes the sense in the maximum map count
check correct.

Add WeightedAvg metric aggregation (#31037)
Adds a new single-value metrics aggregation that computes the weighted 
average of numeric values that are extracted from the aggregated 
documents. These values can be extracted from specific numeric
fields in the documents.

When calculating a regular average, each datapoint has an equal "weight"; it
contributes equally to the final value.  In contrast, weighted averages
scale each datapoint differently.  The amount that each datapoint contributes 
to the final value is extracted from the document, or provided by a script.

As a formula, a weighted average is the `∑(value * weight) / ∑(weight)`

A regular average can be thought of as a weighted average where every value has
an implicit weight of `1`.

Rename ranking evaluation `quality_level` to `metric_score` (#32168)
The notion of "quality" is an overloaded term in the search ranking evaluation 
context. Its usually used to decribe certain levels of "good" vs. "bad" of a 
seach result with respect to the users information need. We currently report the 
result of the ranking evaluation as `quality_level` which is a bit missleading.
This changes the response parameter name to `metric_score` which fits better.

Remove aliases resolution limitations when security is enabled (#31952)
Resolving wildcards in aliases expression is challenging as we may end
up with no aliases to replace the original expression with, but if we
replace with an empty array that means _all which is quite the opposite.
Now that we support and serialize the original requested aliases,
whenever aliases are replaced we will be able to know what was
initially requested. `MetaData#findAliases` can then be updated to not
return anything in case it gets empty aliases, but the original aliases
were not empty. That means that empty aliases are interpreted as _all
only if they were originally requested that way.

Colin Goodheart-Smithe 0edb096eb4 Adds a new auto-interval date histogram (#28993)
* Adds a new auto-interval date histogram

This change adds a new type of histogram aggregation called `auto_date_histogram` where you can specify the target number of buckets you require and it will find an appropriate interval for the returned buckets. The aggregation works by first collecting documents in buckets at second interval, when it has created more than the target number of buckets it merges these buckets into minute interval bucket and continues collecting until it reaches the target number of buckets again. It will keep merging buckets when it exceeds the target until either collection is finished or the highest interval (currently years) is reached. A similar process happens at reduce time.

This aggregation intentionally does not support min_doc_count, offest and extended_bounds to keep the already complex logic from becoming more complex. The aggregation accepts sub-aggregations but will always operate in `breadth_first` mode deferring the computation of sub-aggregations until the final buckets from the shard are known. min_doc_count is effectively hard-coded to zero meaning that we will insert empty buckets where necessary.

Closes #9572

* Adds documentation

* Added sub aggregator test

* Fixes failing docs test

* Brings branch up to date with master changes

* trying to get tests to pass again

* Fixes multiBucketConsumer accounting

* Collects more buckets than needed on shards

This gives us more options at reduce time in terms of how we do the
final merge of the buckeets to produce the final result

* Revert "Collects more buckets than needed on shards"

This reverts commit 993c782d117892af9a3c86a51921cdee630a3ac5.

* Adds ability to merge within a rounding

* Fixes nonn-timezone doc test failure

* Fix time zone tests

* iterates on tests

* Adds test case and documentation changes

Added some notes in the documentation about the intervals that can bbe
returned.

Also added a test case that utilises the merging of conseecutive buckets

* Fixes performance bug

The bug meant that getAppropriate rounding look a huge amount of time
if the range of the data was large but also sparsely populated. In
these situations the rounding would be very low so iterating through
the rounding values from the min key to the max keey look a long time
(~120 seconds in one test).

The solution is to add a rough estimate first which chooses the
rounding based just on the long values of the min and max keeys alone
but selects the rounding one lower than the one it thinks is
appropriate so the accurate method can choose the final rounding taking
into account the fact that intervals are not always fixed length.

Thee commit also adds more tests

* Changes to only do complex reduction on final reduce

* merge latest with master

* correct tests and add a new test case for 10k buckets

* refactor to perform bucket number check in innerBuild

* correctly derive bucket setting, update tests to increase bucket threshold

* fix checkstyle

* address code review comments

* add documentation for default buckets

* fix typo

Circuit-break based on real memory usage
With this commit we introduce a new circuit-breaking strategy to the parent
circuit breaker. Contrary to the current implementation which only accounts for
memory reserved via child circuit breakers, the new strategy measures real heap
memory usage at the time of reservation. This allows us to be much more
aggressive with the circuit breaker limit so we bump it to 95% by default. The
new strategy is turned on by default and can be controlled  with the new cluster
setting `indices.breaker.total.userealmemory`.

Note that we turn it off for all integration tests with an internal test cluster
because it leads to spurious test failures which are of no value (we cannot
fully control heap memory usage in tests). All REST tests, however, will make
use of the real memory circuit breaker.
