We are trying to reduce the logs load in our fleets, and one of the most
recurrent one is
```
Dialing canceled topics="libp2p dialer" tid=1 file=dialer.nim:67 err="Future operation cancelled!" peerId=16U*XAFJX3
```
which is quite spammy and doesn't give much info.
In addition to that, its corresponding `Dialing address` log is in
trace.
So adjusting the log level of `Dialing canceled` to trace :)
