Adrien Grand 866a5459f0 Make significant terms work on fields that are indexed with points. #18031
It will keep using the caching terms enum for keyword/text fields and falls back
to IndexSearcher.count for fields that do not use the inverted index for
searching (such as numbers and ip addresses). Note that this probably means that
significant terms aggregations on these fields will be less efficient than they
used to be. It should be ok under a sampler aggregation though.

This moves tests back to the state they were in before numbers started using
points, and also adds a new test that significant terms aggs fail if a field is
not indexed.

In the long term, we might want to follow the approach that Robert initially
proposed that consists in collecting all documents from the background filter in
order to compute frequencies using doc values. This would also mean that
significant terms aggregations do not require fields to be indexed anymore.

The Elasticsearch docs are in AsciiDoc format and can be built using the
Elasticsearch documentation build process.

See: https://github.com/elastic/docs

Snippets marked with `// CONSOLE` are automatically annotated with "VIEW IN
SENSE" in the documentation and are automatically tested by the command
`gradle :docs:check`. By default `// CONSOLE` snippet runs as its own isolated
test. You can manipulate the test execution in the following ways:

* `// TEST`: Explicitly marks a snippet as a test. Snippets marked this way
are tests even if they don't have `// CONSOLE`.
  * `// TEST[s/foo/bar/]`: Replace `foo` with `bar` in the test. This should be
  used sparingly because it makes the test "lie". Sometimes, though, you can use
  it to make the tests more clear.
  * `// TEST[catch:foo]`: Used to expect errors in the requests. Replace `foo`
  with `request` to expect a 400 error, for example. If the snippet contains
  multiple requests then only the last request will expect the error.
  * `// TEST[continued]`: Continue the test started in the last snippet. Between
  tests the nodes are cleaned: indexes are removed, etc. This will prevent that.
  This is really useful when you have text and snippets that work together to
  tell the story of some use case because it merges the snippets (and thus the
  use case) into one big test.
  * `// TEST[skip:reason]`: Skip this test. Replace `reason` with the actual
  reason to skip the test. Snippets without `// TEST` or `// CONSOLE` aren't
  considered tests anyway but this is useful for explicitly documenting the
  reason why the test shouldn't be run.
  * `// TEST[setup:name]`: Run some setup code before running the snippet. This
  is useful for creating and populating indexes used in the snippet. The setup
  code is defined in `docs/build.gradle`.
* `// TESTRESPONSE`: Matches this snippet against the body of the response of
  the last test. If the response is JSON then order is ignored. With
  `// TEST[continued]` you can make tests that contain multiple command snippets
  and multiple response snippets.
  * `// TESTRESPONSE[s/foo/bar/]`: Substitutions. See `// TEST[s/foo/bar]`.
* `// TESTSETUP`: Marks this snippet as the "setup" for all other snippets in
  this file. This is a somewhat natural way of structuring documentation. You
  say "this is the data we use to explain this feature" then you add the
  snippet that you mark `// TESTSETUP` and then every snippet will turn into
  a test that runs the setup snippet first. See the "painless" docs for a file
  that puts this to good use. This is fairly similar to `// TEST[setup:name]`
  but rather than the setup defined in `docs/build.gradle` the setup is defined
  right in the documentation file.

Any place you can use json you can use elements like `$body.path.to.thing`
which is replaced on the fly with the contents of the thing at `path.to.thing`
in the last response.
