…tity fields (#801)

Add new identity fields for agentless, and make them mandatory.
This is a breaking change, but there are very few affected integrations.

Knowledge base entries are a new type of content that provides information for AI assistants.

A knowledge base entry in a package is composed of 3 parts:
* A manifest.yml file
* A fields folder, containing one or more fields files
* A content folder, containing one or more content files, containing the ES documents of
  the knowledge base in an NDJSON format.

Add a new validation check to ensure that the first (newer) changelog
entry defined in the changelog file is not lower than the other versions
according to the Semantic Versioning.

This feature won't be likely released on this form. Reverting it by now.
