Support the 'fields' option in inner_hits and top_hits. (#62337)
This PR adds support for the 'fields' option in the following places:
* Anytime `inner_hits` is used, for both fetching nested/ child docs and field collapsing
* The `top_hits` aggregation

[DOCS] http -> https, remove outdated plugin docs (#60380) (#60545)
Plugin discovery documentation contained information about installing
Elasticsearch 2.0 and installing an oracle JDK, both of which is no
longer valid.

While noticing that the instructions used cleartext HTTP to install
packages, this commit replaces HTTPs links instead of HTTP where possible.

In addition a few community links have been removed, as they do not seem
to exist anymore.

[7.x] Histogram field type support for ValueCount and Avg aggregations (#56099)
Backports #55933 to 7.x

Implements value_count and avg aggregations over Histogram fields as discussed in #53285

- value_count returns the sum of all counts array of the histograms
- avg computes a weighted average of the values array of the histogram by multiplying each value with its associated element in the counts array

Preserve metric types in top_metrics (backport of #53288) (#53440)
This changes the `top_metrics` aggregation to return metrics in their
original type. Since it only supports numerics, that means that dates,
longs, and doubles will come back as stored, with their appropriate
formatter applied.

Implement top_metrics agg (#51155) (#52366)
The `top_metrics` agg is kind of like `top_hits` but it only works on
doc values so it *should* be faster.

At this point it is fairly limited in that it only supports a single,
numeric sort and a single, numeric metric. And it only fetches the "very
topest" document worth of metric. We plan to support returning a
configurable number of top metrics, requesting more than one metric and
more than one sort. And, eventually, non-numeric sorts and metrics. The
trick is doing those things fairly efficiently.

James Rodewig 1299dda437 [DOCS] Warn about using `geo_centroid` as sub-agg to `geohash_grid` (#50038)
If `geo_point fields` are multi-valued, using `geo_centroid` as a
sub-agg to `geohash_grid` could result in centroids outside of bucket
boundaries.

This adds a related warning to the geo_centroid agg docs.

James Rodewig 694b119f0a [DOCS] Percentile aggs are non-deterministic (#50468)
Percentile aggregations are non-deterministic. A percentile aggregation
can produce different results even when using the same data.

Based on [this discuss post][0], the non-deterministic property stems
from processes in Lucene that can affect the order in which docs are
provided to the aggregation.

This adds a warning stating that the aggregation is non-deterministic
and what that means.

James Rodewig 364eb2d34c [DOCS] Correct percentile rank agg example response (#50052)
The example snippets in the percentile rank agg docs use a test dataset
named `latency`, which is generated from docs/gradle.build.

At some point the dataset and example snippets were updated, but the
text surrounding the snippets was not. This means the text and the
example snippets shown no longer match up.

This corrects that by changing the snippets using /TESTRESPONSE magic comments.

[7.x] Implement stats aggregation for string terms (#49097)
Backport of #47468 to 7.x

This PR adds a new metric aggregation called string_stats that operates on string terms of a document and returns the following:

min_length: The length of the shortest term
max_length: The length of the longest term
avg_length: The average length of all terms
distribution: The probability distribution of all characters appearing in all terms
entropy: The total Shannon entropy value calculated for all terms

This aggregation has been implemented as an analytics plugin.

Expose sequence number and primary terms in search responses (#37639)
Users may require the sequence number and primary terms to perform optimistic concurrency control operations. Currently, you can get the sequence number via the `docvalues_fields` API but the primary term is not accessible because it is maintained by the `SeqNoFieldMapper` and the infrastructure can't find it. 

This commit adds a dedicated sub fetch phase to return both numbers that is connected to a new `seq_no_primary_term` parameter.
