Bug Description
See: https:/
Dear distributors,
In the last few days, we have been looking into mitigating the impact
of Discover against certain KDE web services.
Some of the problems can be addressed in the service itself but not
them entirely, so it would be useful if the following changes were
backported into your own packaging. We have already included it in our
stable branches but on the distributions that ship unsupported
versions of our software it would be useful you can apply these
patches.

If you feel unsure about the patch on a specific branch, feel free to
contact me here or in private and I will backport it if necessary.
Impact]
* Effectively a DDOS on some KDE servers that were not intended to take this traffic
[Test Plan]
* Test that Discover functions normally with the changes. e.g. KNS, packagekit, snap backends work as intended.
[Where problems could occur]
* Could fail to fetch resources, crash etc. It will need to be tested with a reasonable sample of these that this does not happen.
