Bugzilla

I'm thinking:

1. Catch `ERROR` in the response and treat it as a failure
2. Potentially switch to single zip rather than sudo+notary accounts+1 zip per locale. This change will:
    a. remove the need for notary accounts, simplifying setup
    b. reduce our concurrent uploads by ~80%
    c. potentially slightly slow down the all-good poller case, but drastically reduce or remove the multi-hour manual intervention lost UUID case.

Going to test the single zip manually.

    d. if it resolves the lost UUID issue completely, we can drop the planned added complexity to the poller and resolve this bug.

Going to test the single zip manually, by [manually rerunning a task](https://github.com/mozilla-releng/scriptworker-scripts/wiki/Testing-iscript#directory-tree) after setting `notarize_type` to `single_zip`.
