If letsencrypt returns 503 acmetool returns unrelated errors

[Mrten]

Letsencrypt is returning 503's at the moment and when running acmetool it returns unrelated errors:

20161031114637 [ERROR] acme.storageops: Target([...];https://acme-staging.api.letsencrypt.org/directory;0): failed to request certificate: HTTP error: 503 Service Unavailable

(slightly edited)

The last error-line is returned for each and every target.
