feat: Ignore specific errors for given pods

[nikup]

Add support for ignoring a specific restart error for a specific type of pod. Example: We have a gke-metrics-agent that sometimes can't start because of Failed to run the service: failed to start extensions: listen tcp 127.0.0.1:8203: bind: address already in use. With the current implementation we can ignore that by adding

ignoredErrorsForPodNamePrefixes = "{ "gke-metrics-agent": [ "address already in use" ]}"
