[INF-4803] StatusPage component

Jira Ticket Link / Motivation

Supersedes #421 by replacing the embedded status icon from ably.com/status/embed/icon with a React component that fetches the status from the statuspage.io API for us

Summary of changes

• New Status component, requires the statusUrl to be set to work reliably
• Added stories for the Status component so we view the different states
• Replaced the iframe in the Footer and Meganav components with the Status

See commits for details

How do you manually test this?

Pull, run storybook, and view the Status components

Looks pretty good, just a couple of things, can we also bump the package.json version to 14.2.0?
