[GOT-19] Propose a architectural design of decentralized metrics collection

[brunocalza]

• You should experiment with go libp2p library
• You can peek at other projects to see how they do it
• Maybe you can start with some simple ping example and build on top of that

// P2P Metrics
PeerCount         prometheus.Gauge
StreamCount       prometheus.Gauge
PeerScores        *prometheus.GaugeVec
GossipEventsTotal *prometheus.CounterVec
BandwidthTotal    *prometheus.GaugeVec

They have an interface called Metricer that indicates all kind of metrics being collected from peers
