Mitigate cache invalidation issues with a reduced default expiration time.
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can no longer invalidate / clear out the cache appropriately while it is offline, and when it comes back up it will be out of date.
We should mitigate this by reducing the default expiration time while investigating more comprehensive solutions.

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.
