Backports for 9.10.4

I've started to work on preparing the 9.10.4 release. If you have patches that you think should be backported please apply the backport needed 9.10 label to the MR in question in a timely fashion. If you have other concerns about this release similarly please reach out and let me know. Currently we plan for this to be the last 9.10 release in the 9.10 series. Cheers Andreas
