Title: When fail-under condition is not met, log the error.

@Bachmann1234 @wedaly

We use diff-cover as a child process. If we use the fail-under flag, we could use some more logging. (The end-users may not know we're imposing a cover/quality limit, and if they do, they may not know what the limit is.)
