Pre-Merge PR: https://github.com/quay/quay/pull/4382

Quay Config:  local-dev/stack/config.yaml

FEATURE_IMAGE_PULL_STATS: true

Steps:

1. Set FEATURE_IMAGE_PULL_STATS: true  
   change config.py REDIS_FLUSH_INTERVAL_SECONDS = 30
2. Push alpine/busybox 2 images to repository A on localhost:8080 
3. Pull alpine 3 times, busybox 1 time from repo A
4. Push the same alpine/busybox to repository B   
5. Pull image alpine, busybox from repo B
6. Check repo B tag status on New UI   

Result:

In repo A "Last Pulled" and "Pull Count" status is correct, but in repo B it always null

repo B ->

Comments:

Another case: Push image redis to repo A, then repo B, pull from any repo, both keep null
