flakey behavior using Dockerhub credentials for ImageRepository

[jwtracy]

I have valid .dockerconfigjson credentials in an image pull secret I'm using for an ImageRepository.

This works a lot of the time but not all the time. eg:

Events:
  Type     Reason               Age                  From                        Message

nauthorized: {"details":"incorrect username or password"}

I'm not sure why this is. My imagerepository.spec.interval is set to 10 min. Could this be too frequent? I am not seeing 429 errors from Dockerhub.

Loving the image controllers suite of tools but could use some help getting this more reliable. Will take a look at the code myself if I have the time this week or next.
