chore: setting dialing canceled log to trace

[gabrielmer]

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 :)

Can this be merged?

[gabrielmer]

I'm not being able to merge it because of the failing CI (which is not related to the PR).

@AlejandroCabeza is there any way to merge it?

@kaiserd I temporarily marked the "transport interoperability tests" job as non-required as it's been broken for some time and preventing PRs from being merged, but it needs to be fixed.
