RC 0.2.0

[nodiesBlade]

Github issue

Description

• Fixes typo in is_heathy -> is_healthy in qosnodes endpoint (reason for the minor version upgrade)
• Adds node_public_key to qosnodes endpoint to enable Poktscan to scrape data and provide QoS data publically
• Fix incorrect timeout setting and clarify env var docs #29
• Adds more tags to relayer prometheus metrics (chain id) and for histogram latency (chain id, altruist, and success) for increased observability oversight.
• Add pocket_relay_latency prom metric to keep track of latency for simply sending a relay to the network (no qos/node selection)
• Improve QoS data integrity check by checking if the selected source of truth returns an actual block hash (otherwise skip and try again)
• Change module to github.com/pokt-network/gateway-server to match github repoistory now that we've transitioned it over to the Foundation. This allows others to import the v0 client pkg and other pkgs in the future.
• Includes updated benchmarking doc with RC 0.2.0

Type of change
