Describe the rate limiting feedback for peers #66

Problem

Due to using a low PoW, Status nodes and clients are vulnerable to a denial of service attack.

It's not possible to increase PoW because of mobile usage. The alternative is an implementation of rate limiting.

Solution

Describe in the spec, how rate limiting would work. It should take into consideration:

the general algorithm
rate limiting settings on the client and server
how rate limiting information is broadcasted to peers (similar to broadcasting PoW and bloom filters settings)
rate limiting information in the handshake.
