Allow three types of node metadata output onto chain

[mrtingalingling]

          We will likely have three types of node metadata on chain: 

1. NFT <-> Node un/registration (Alpha)
2. Node access config (e.g. how much bandwidth to allocate, domain blocklist, etc - Beta)
3. Node Status (e.g. How much bandwidth is available, this will likely be periodically pushed from the Node Binary [I am thinking every 30 min as well as whenever someone inquires the DHT that contains this node if the node's latest status remain qualified for access] - MVP)
