Some of the errors we were considering as retryable were not really retryable. For example, if a metadata server produced an
ECONNRESET
error, most of the time it was an error that happened consistently even when retrying after a while. Since we're running in strict mode, this caused an inifite retry of these jobs which makes no sense.Because of this, this PR only leaves temporary Stacks node errors and 429 rate limit errors to be infinitely retryable because they are (almost) guaranteed to be resolved after a number of retries.
