• 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.
• Improve QoS data integrity check by checking if the selected source of truth returns an actual block hash (otherwise skip and try again)
