## Summary

This extracts the Observability AI Assistant into a shared package so
Search and Observability can both consume it.

A few notes:

This still relies on significantly tight coupling with the Obs AI
assistant plugin, which we will want to slowly decouple over time. It
means that currently to consume this in multiple places, you need to
provide a number of plugins for useKibana. Hopefully we can get rid of
that and replace them with props eventually and make the interface a
little less plugin-dependent.
