If you have a protected path in your clean targets, log that the file can't be cleaned.

Describe the feature

If I run dbt clean the output indicates that a file is checked and then that a file is cleaned. If it cannot clean the file, it doesn't indicate that way.
I propose adding a simple message that says [file] can't be cleaned

Describe alternatives you've considered

Technically speaking you can tell that something is wrong because you don't get the affirmation that the path is cleaned, but it seems to make sense to me to be more explicit.

Additional context

Who will this benefit?

Anyone who runs dbt clean
