[Bug]: Confusing error message when Docker is not able to push the image

[vvagaytsev]

Bug

Current behavior

The error looks like this:

✖ build.vote                → Failed (took 1.5 sec)
ℹ test.vote-unit            → Aborting because upstream dependency failed.
✖ build.vote                → Failed processing Build type=container name=vote (from module vote) (took 2.63 sec). This is what happened:

──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
ERROR: denied: Your authorization token has expired. Reauthenticate and try again.
──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────

Expected behavior

More context should be given in the error message, namely that docker build failed, and a few lines before the error happened (so users understand that it failed to push to the registry).
