Edit required_fields field for custom rules in UI and API

[nikitaindik]

Description

This documentation request is basically a clone of the "related_integrations" documentation request, but for "required_fields".

We are wrapping up the work on the PR that adds an ability to add and edit rule's required fields. "Required fields" is an optional field that shows the user which Elasticsearch fields are needed for the rule to run properly. Currently required fields are hardcoded in Elastic prebuilt rules. Once this PR is merged, users will be able to modify required fields for custom rules.
