Increase expiration time for the merge request api cache

What does this MR do?

In the other merge request ot increase the expiration time from 15 minutes to 12 hours we saw a positive effect on the api request timings. There seems to be calls that make a request every 24 hours, so by setting the cache to 25 hours, we should catch these.
