Use a logger

[sipsma]

Our loggers are currently fmt and panic. Dagger uses zerolog, so unless we have reason to not want to use it again (cc @aluzzardi), we should configure it in cloak too. At the very minimum it would be nice to start writing informational+debug logs.

One note from Andrea: "The buildkit progressui is not that great, and moving to zerolog requires porting progressui over
(otherwise they fight for the terminal, not pretty)"

This is being tracked here now #3587
