Custom fleet policy UX for new integration (cloud defend v1) (#147300)

## Summary

New Kibana plugin created for an integration called "Cloud defend for
containers" which will have a corresponding agent service which can
proactively block and alert on executable creation or modification in a
running container.

This plugin is purely in place to configure the fleet policy UX around
this new integration. For now we have added a yaml editor as a custom
input to our integration. The monaco-yaml libary was added to allow
support for JSON schema validation support for yaml.

Integration PR is up, and a work in progress: (waiting on some content
for the doc page)
