improvement: less scary failed conn logs & metrics

Browse source 
...and adjust the `totalFailedConnections` metric name
and description.

This commit should make the periodic stats log messages
and the relevant metric look less scary to users:
P2P connection failures are relatively frequent and are usually
not indicative of the proxy operator having done something wrong.
So let's tone the wording down.

See the discussion: https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/merge_requests/516#note_3173677.
