Make abortOnError packageRules-configurable, not hostRules

What would you like Renovate to be able to do?

Give users more control and visibility about when a run should be aborted due to external host errors

If you have any ideas on how this should be implemented, please tell us here.

This requires https://github.com/renovatebot/renovate/issues/21752 first.

If we shift to packageRules, we may need to add a matchRegistryUrls matcher to packageRules first.

We also should consider whether to make this multi-dimensional, e.g.

• A field to flag a particular package or registry as "critical"
• Another field to denote how to handle such critical failures, e.g.
  • Keep going anyway, but warn
  • Keep going anyway, warn and skip branch pruning (autoclosing)
  • Abort the run

Is this a feature you are interested in implementing yourself?

No
