This commit allows you to set 'script' and 'on_script_error' parameters
on date field mappers, meaning that runtime date fields can be made indexed
simply by moving their definitions from the runtime section of the mappings
to the properties section.
We accept dates with a decimal point like `2113413.13241324` and parse
them *somehow*. But there are cases where we'll lose precision on those
dates, see #70085. This advises folks not to use that format. We'll
continue to accept those dates for backwards compatibility but you
should avoid using them.

* Warn users if security is implicitly disabled (#70114)
Elasticsearch has security features implicitly disabled by default for
Basic and Trial licenses, unless explicitly set in the configuration
file.
This may be good for onboarding, but it also lead to unintended insecure
clusters.
This change introduces clear warnings when security features are
implicitly disabled.
- a warning header in each REST response if security is implicitly
disabled;
- a log message during cluster boot.
Runtime fields are much more flexible than script_fields because you
can filter and aggregate on them so we hope folks use them! This
converts the example of using a `parent_join` field in a script to a
runtime field so folks get used to seeing them and hopefully using them.
While I was editing this I took the opportunity to replace the script
with a real-ish example. Scripts that just load the field value are nice
and short but I hope no one uses them in real life because they just add
overhead when compared to accessing the field directly. So I made the
script do something.

This shrinks a runtime field definition so that it fits on the screen
without scrolling. It also converts the doc into a test so we can be
sure it continues to work.

This commit allows you to set 'script' and 'on_script_error' parameters
on IP field mappers, meaning that runtime IP fields can be made indexed
simply by moving their definitions from the runtime section of the mappings
to the properties section.

We have recently introduced the ability to associate an indexed field with a script. This commit updates the existing mappings stats to output stats about the script, similar to what we already do for runtime fields.

Today the response to `GET _cluster/state` does not include the roles of
the nodes in the cluster. In the past this made sense, roles were
relatively unchanging things that could be determined from elsewhere.
These days we have an increasingly rich collection of roles, with
nontrivial BWC implications, so it is important for debugging to be able
to see the specific roles as viewed by the master. This commit adds the
role names to the cluster state API output.

This commit adds a deprecation note to the multiple data paths doc. It also removes mention of multiple paths support in the setup settings table.

This adds a "note" on the docs for the script query pointing folks to
runtime fields because they are more flexible. It also translates the
request example into runtime fields.

This replaces the `script` docs for bucket aggregations with runtime
fields. We expect runtime fields to be nicer to work with because you
can also fetch them or filter on them. We expect them to be faster
because their don't need this sort of `instanceof` tree:
