Today there is a lot of code duplication and different handling of errors in the two different scroll modes. Yet, it's not clear if we keep both of them but this simplificaiton will help to further refactor this code to also add cross cluster search capabilities. :

There was a problem hiding this comment.
useless return statement? or maybe future-proof? in the latter case we should do the same above in innerOnResponse?

this really also turned into a bugfix. the error handling in the old impls where totally lenient when nodes died between reqeust. I will need to add unittests too. I will push more stuff later |

This refactoring also fixes bugs when shards failed due to the node dropped out of the cluster in between scroll requests and failures during the fetch phase of the scroll. Both places where simply ignoring the failure and logging to debug. This can cause issues like #16555
