Add Individual Hardware Information to Telemetry Feed

[wpank]

Right now all the new hardware information gets aggregated and sent in the ChainStatsUpdate feed message.

For things like the thousand validators programme, having this hardware data on a per node basis will help a lot with nominations, monitoring network health, and debugging.

For now I think it would be good to add this to the AddedNode Message, as this is what will get sent upon subscribing to the feed.

It would help to include three new messages:

• NodeSysInfo
• NodeHwBench
• IP Address

The IP Address part is also useful for determining infrastructure providers via various different apis.

This issue prompted me to add #480.

I'd love to know precisely what information you currently want to obtain from telemetry over in that issue, so that we can see how easy/difficult it might be to expose a properly supported API that is separate from the frontend feed.
