bug: go-waku logs zone-sensitive time

[igor-sirotin]

Problem

Status user reported there're some logs that use local timezone, which exposes user's location.
I fixed a few in status-go, but there're some in go-waku as well:

go-waku/waku/v2/peermanager/peer_connector.go

Line 210 in 19a47a1

zap.Time("currentTime", now), zap.Time("until", tv.nextTry))

go-waku/waku/v2/peermanager/peer_connector.go

Line 214 in 19a47a1

zap.Time("currentTime", now), zap.Time("nextTry", tv.nextTry))

go-waku/waku/v2/peermanager/peer_connector.go

Line 231 in 19a47a1

logging.HostID("peerID", peerID), zap.Time("until", cachedPeer.nextTry))

Solution

When logging, we should always convert time to UTC.

@igor-sirotin included a fix in #1192 .

If we need this as part of current release, then i will create a PR for release branch cherry-picking this commit.

@chaitanyaprem thanks for the fix!

Though it's a simple fix, I don't like to harass cherry-picking that much.
And I didn't cherry-pick this fix as well: status-im/status-go#5672
