## 📓 Summary

Closes elastic/logs-dev#165

This work introduces a Summary column as a replacement for the Document
one for the Discover logs contextual experience.
> We also decided to port this change as a replacement for the
**resource** and **content** virtual columns in Logs Explorer to have a
better alignment between the 2 apps.

## 💡 Reviewer hints

I left notes through the changes to help answer some questions.

The notable changes on this PR are:
- Rename `Document` column to `Summary`.
- Refactor `resource` and `content` virtual columns into a single
`Summary` column, which replaces the default Summary content for the
logs' contextual experience.
- Provide support for the plugin services to the context awareness
profiles.
- Disable virtual columns (clean up will go in a follow-up work) in Logs
Explorer and rely on the Summary column as the default selection.
