Core-side retries on curl errors have been explicitly disallowed in the past in #3712 to protect from double writes in case of errors in a connection teardown phase, so after a fragment has been written, where a retry would just re-write the same fragment.

However, we have experienced spurious "Connection reset by peer" type of errors especially during ingestion (Write queries), which we think could be mitigating by allowing retries for most of curl errors. (exclude those that typically happen during connection teardown).

[sc-54377]


TYPE: IMPROVEMENT
DESC: Enable curl error retries.

@teo-tsirpanis we might have to but we might get rid of the current release-2.27 branch so let's not do it now.
