Update use of Packet to Equinix Metal

[michaelspedersen]

As the title states, Packet has been renamed Equinix Metal

At this time I am not sure if this will have implications for the use of existing APIs, but I know that "Packet" is mentioned a lot throughout documentation.

TODO:

• [ ] Verify that API endpoints are still working (and update if needed)
• [ ] Update documentation to reflect the change in name

@michaelspedersen new URLs:

• Website: https://metal.equinix.com
• Support: support@equinixmetal.com
• Portal: https://console.equinix.com 
• Status: https://status.equinixmetal.com 
• API: https://api.equinix.com/metal/v1 

As of now, it looks like the DNS for api.packet.net still works:

I recommend we update the API URL used across the code base sooner than later, but I don't consider it urgent at this time.

app.packet.net redirects to https://console.equinix.com. You can log in to the console.equinix.com using your app.packet.net credentials.
