Hi @grzesuav , would you be able to rerun the failing actions on this PR? I am able to run them successfully locally so I am not sure if there is just some flakiness going on or if my change would have any impact on the failiures. |

The purpose of this PR is to avoid completely failing API discovery if only a subset of resources fail to be fetched.
In my particular case, another team managing keda-operator-metrics-apiserver occasionally goes into a bad state causing an error discovery resources. If metacontroller is starting up for the first time, then it will get an error fetching resources and be blocked until the keda operator is in a good state and responds with resources during API discovery.
