@michaelsproul found that the BEACON_BLOCK_DELAY_GOSSIP metric is recorded before the block is verified:

lighthouse/beacon_node/network/src/network_beacon_processor/gossip_methods.rs

Lines 910 to 919 in d84e3e3

metrics::set_gauge(
&metrics::BEACON_BLOCK_DELAY_GOSSIP,
block_delay.as_millis() as i64,
);
let verification_result = self
.chain
.clone()
.verify_block_for_gossip(block.clone())
.await;

This causes the metric could record a time in the range minutes-hours if an old block is received, see https://discord.com/channels/605577013327167508/746918775919738893/1255734712971038810

This PR fixes it so that the metric is only recorded after the block is verified.

Thanks @michaelsproul !
