Add warning events for service account OAuth configuration errors to aid in troubleshooting. Display these events when describing service accounts.

You're sending one event per oauth login to the master? That's... probably going to eat into our write budget.

Sort of? We cannot do validation on SA annotations. This lets the user know if something looks off.

You're sending one event per oauth login to the master? That's... probably going to eat into our write budget.

Based on some offline discussions with Jordan, I plan to change this to send a single warning event when something looks incorrect. That event would contain a sorted list of problems noticed. Thus if the user goes through the same error flow multiple times, the same event should just have its counter incremented. No events will be generated when everything is working as expected.

incrementing a counter is still an etcd write.

@liggitt what do you expect to happen when non-fatal errors are encountered in a GetClient flow? I am mostly envisioning a scenario where a user has annotation for redirect uris X and Y, but only Y is "broken." Thus GetClient will succeed and the user could encounter an OAuth error if Y is used. I feel like we have forcibly limited the events from spamming enough that it should be OK to always create an event for any errors encountered (and rely on the event rate limiting to prevent us from ever doing more than one event per minute).

I would expect coreClient.Events("") or if that does not work then:
