Failure in the case of not-found-while-deleting is subjective IMO. You can
look at it as "the processor did not perform the task I issued", or "the
processor accomplished the end goal of the task (i.e. the document is not there
after the delete)". It seems ES is choosing the latter, but if a general user
would expect a "failed delete" along the failure relationship, we can treat
them as such.

> If it cannot extract the reason text it provides a very generic error and
> there is nothing else logged. You get no context as to what went wrong and
> further the condition doesn't cause yielding or anything so there is just a
> massive flood of errors in logs that dont' advise the user of the problem.
> We need to make sure the information can be made available to help
> troubleshoot and we need to cause yielding so that such cases do not cause
> continuous floods of errors.
