KRR computes recommendation for lots of Kubernetes objects, but if just one errors out no results are printed

Describe the bug
KRR computes recommendations for lots of Kubernetes objects but if just one errors out, no useful results are printed.

To Reproduce
Steps to reproduce the behavior:

1. Have an unstable Prometheus cluster
2. Run krr simple
3. Observe that even though lots of INFO Calculated recommendations for ... lines are printed, if one object errors out, none of these recommendations are printed, only the error/traceback is printed.

Expected behavior
A partial result is printed with the recommendations of the objects for which KRR was able to compute, and a list of errors for the objects that had errors.

Are you interested in contributing a fix for this?

Strongly in favor of a fix! It would be best to do it on top of the prometheus-workload-loader branch as that has some major changes that will be merged soon.

We would love to receive a PR for this.

Hey, I had an easy test case for this so I fixed it myself. Please test and confirm that this works.

Note that the fix isn't merged yet - it is on #307
