Implement a blacklisting mechanism for libp2p peers

[richard-ramos]

Some peers are causing an increase in CPU usage when they connect/disconnect. I have identified two of them which spiked the processor to 100%.

murmur/src/libp2p-node.js

Line 142 in 58a0cfa

if(peer.id.toB58String() !== "QmNo4aCrDJkwg7V1t28kp6EehNVYX3DkTa2UAdi9UaS4Vw" ||

Implement a blacklisting mechanism that after N reconnect attempts in a period of time, will stop murmur from invoking: this.node.dial(peer, () => { });.
