Remove HTTP max content length leniency (#29337)
I am not sure why we have this leniency for HTTP max content length, it
has been there since the beginning
(5ac51ee93f) with no explanation of its
source. That said, our philosophy today is different than the philosophy
of the past where Elasticsearch would be quite lenient in its handling
of settings and today we aim for predictability for both users and
us. This commit removes leniency in the parsing of
http.max_content_length.

Clarify expectations of false positives/negatives (#27964)
Today this part of the documentation just says that Geo queries are not 100% 
accurate, but in fact we can be more precise about which kinds of queries see
which kinds of error. This commit clarifies this point.

Update docs on vertex ordering (#27963)
At time of writing, GeoJSON did not enforce a specific ordering of vertices in
a polygon, but it now does. We occasionally get reports of Elasticsearch
rejecting apparently-valid GeoJSON because of badly oriented polygons, and it's
helpful to be able to point at this bit of the documentation when responding.

Boaz Leskes eb8b31746a Move trimming unsafe commits from engine ctor to store (#29260)
As follow up to #28245 , this PR removes the logic for selecting the 
right start commit from the Engine constructor in favor of explicitly
trimming them in the Store, before the engine is opened. This makes the
constructor in engine follow standard Lucene semantics and use the last
commit.

Fold EngineDiskUtils into Store, for better lock semantics (#29156)
#28245 has introduced the utility class`EngineDiskUtils` with a set of methods to prepare/change
translog and lucene commit points. That util class bundled everything that's needed to create and
empty shard, bootstrap a shard from a lucene index that was just restored etc. 

In order to safely do these manipulations, the util methods acquired the IndexWriter's lock. That
would sometime fail due to concurrent shard store fetching or other short activities that require the
files not to be changed while they read from them. 

Since there is no way to wait on the index writer lock, the `Store` class has other locks to make
sure that once we try to acquire the IW lock, it will succeed. To side step this waiting problem, this
PR folds `EngineDiskUtils` into `Store`. Sadly this comes with a price - the store class doesn't and
shouldn't know about the translog. As such the logic is slightly less tight and callers have to do the
translog manipulations on their own.

Optimize the composite aggregation for match_all and range queries (#28745)
This change refactors the composite aggregation to add an execution mode that visits documents in the order of the values
present in the leading source of the composite definition. This mode does not need to visit all documents since it can early terminate
the collection when the leading source value is greater than the lowest value in the queue.
Instead of collecting the documents in the order of their doc_id, this mode uses the inverted lists (or the bkd tree for numerics) to collect documents
in the order of the values present in the leading source.
For instance the following aggregation:

```
"composite" : {
  "sources" : [
    { "value1": { "terms" : { "field": "timestamp", "order": "asc" } } }
  ],
  "size": 10
}
```
... can use the field `timestamp` to collect the documents with the 10 lowest values for the field instead of visiting all documents.
For composite aggregation with more than one source the execution can early terminate as soon as one of the 10 lowest values produces enough
composite buckets. For instance if visiting the first two lowest timestamp created 10 composite buckets we can early terminate the collection since it
is guaranteed that the third lowest timestamp cannot create a composite key that compares lower than the one already visited.

This mode can execute iff:
 * The leading source in the composite definition uses an indexed field of type `date` (works also with `date_histogram` source), `integer`, `long` or `keyword`.
 * The query is a match_all query or a range query over the field that is used as the leading source in the composite definition.
 * The sort order of the leading source is the natural order (ascending since postings and numerics are sorted in ascending order only).

If these conditions are not met this aggregation visits each document like any other agg.

Add new setting to disable persistent tasks allocations (#29137)
This commit adds a new setting `cluster.persistent_tasks.allocation.enable`
that can be used to enable or disable the allocation of persistent tasks.
The setting accepts the values `all` (default) or `none`. When set to
none, the persistent tasks that are created (or that must be reassigned)
won't be assigned to a node but will reside in the cluster state with
a no "executor node" and a reason describing why it is not assigned:

```
"assignment" : {
  "executor_node" : null,
  "explanation" : "persistent task [foo/bar] cannot be assigned [no
  persistent task assignments are allowed due to cluster settings]"
}

Update allocation awareness docs (#29116)
Update allocation awareness docs

Today, the docs imply that if multiple attributes are specified the the
whole combination of values is considered as a single entity when
performing allocation. In fact, each attribute is considered separately. This
change fixes this discrepancy.

It also replaces the use of the term "awareness zone" with "zone or domain", and
reformats some paragraphs to the right width.

Untangle Engine Constructor logic (#28245)
Currently we have a fairly complicated logic in the engine constructor logic to deal with all the 
various ways we want to mutate the lucene index and translog we're opening.

We can:
1) Create an empty index
2) Use the lucene but create a new translog
3) Use both
4) Force a new history uuid in all cases.

This leads complicated code flows which makes it harder and harder to make sure we cover all the 
corner cases. This PR tries to take another approach. Constructing an InternalEngine always opens 
things as they are and all needed modifications are done by static methods directly on the 
directory, one at a time.

Joost Rothweiler 02a611663a Indices PUT Mapping API docs: Remove mapping type user and rephrase first sentence (#28998)
The current docs on [Indices APIs: PUT Mapping](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-put-mapping.html) suggests that a having number of different mapping types per index is still possible in elasticsearch versions > 6.0.0 although they have been [removed](https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html). The console code has already been updated accordingly but notes (2) and (3) on the console code still name the `user` mapping type.

This PR updates the list with notes after the console code, as well as the first sentence of the docs
to avoid confusion. Also, I have removed the second command from the console code as it no
longer holds any value if the docs are solely on the `_doc` mapping.

Remove leftover doc comment on client JVM check
We previously specified the -server flag to force the JVM to use the
server JVM. This is the default on all the systems that we support when
using a 64-bit JVM (and we no longer support 32-bit JVMs). There was
some trouble with this flag for the Windows service since procrun did
not understand what to do with it; as such, we had to filter this flag
out in the service. When we migrated to parsing JVM options in Java (via
the JVM options parser) we simplified this situation and removed
specifying the -server flag. This commit removes a leftover statement
that we are forcing the server JVM.

new one (deleting existing files). This PR separates these two into separate code paths. The
constructors opens files and a dedicated static methods creates an empty translog.

Search option terminate_after does not handle post_filters and aggregations correctly (#28459)
* Search option terminate_after does not handle post_filters and aggregations correctly

This change fixes the handling of the `terminate_after` option when post_filters (or min_score) are used.
`post_filter` should be applied before `terminate_after` in order to terminate the query when enough document are accepted
by the post_filters.
This commit also changes the type of exception thrown by `terminate_after` in order to ensure that multi collectors (aggregations)
do not try to continue the collection when enough documents have been collected.

Search - add allow_partial_search_results flag with default setting false (#28440)
Adds allow_partial_search_results flag to search requests with default setting = true.
When false, will error if search either timeouts, has partial errors or has missing shards rather
than returning partial search results. A cluster-level setting provides a default for search requests with no flag.

Add ranking evaluation API to High Level Rest Client (#28357)
This change adds support for the new ranking evaluation API to the High Level Rest Client.
This mostly means adding support for parsing the various response objects back from the
REST representation. It includes one change to the response syntax where previously we didn't
print the type of the metric details section but we now need it to pick the right parser to
parse this section back.
