Description

If Redis goes down, Pulp can no longer invalidate / clear out the cache appropriately while it is offline, and when it comes back up it will be out of date.

Reduce the cache entry expiration TTL

If Redis goes down then its persisted data can get out of sync with Pulp, because cache invalidation events cannot occur. We should mitigate the impact by letting cache entries expire after a shorter period of time.
