[DOCS] Response console UI for endpoint actions

[joepeeples]

Description

Create docs for the new response console UI, which allows users to perform response actions on an endpoint using a console-like shell UI. Users can enter action commands and get near-instant feedback on them. Actions are also logged in the endpoint's activity log (Endpoint details flyout > Activity Log tab).

Initially, response console will support host isolation/release actions, with additional actions in future iterations. Refer to related meta and its many issues, PRs, etc. for various features:
