[WIP] SIP-0006 and SIP-0007

This PR will propose two new SIPs.

SIP-0006 "Distributed Identity Directory" (discover child identities associated with public extended key via authenticated index insertion into the DHT)
SIP-0007 "Peer Performance Measurement" (track performance indicators from other nodes and share with other nodes to establish collaborative filter)

[ ] Directory information storage for discovering child nodes of a given xpubkey
- Use the DHT to store child indexes by xpubkey hash
- Author as SIP - implement as plugin
- https://github.com/Storj/sips/pull/15
[ ] Consensus mechanism for new farmer ramp-up and peer measurement of performance
- Tor does this well https://blog.torproject.org/blog/lifecycle-of-a-new-relay
- Exchange reports should be reconsidered - Storj Labs should not be the single source of truth
- Author as SIP - implement as plugin
- https://github.com/Storj/sips/pull/15
