MAI Connectors: Use absolute expiration when caching entity data.

Description

The MAI connectors store entity data in a cache with a sliding expiration of 10 minutes.
This causes an issue where if the data is updated directly on the provider portal itself (as opposed to updating via form submission), it won't be reflected on personalized blocks and form auto-fill unless the cache is not accessed in the cache expiration interval of 10 minutes.

This behavior has been changed from version 5.6.3, by setting the cache to expire after a fixed interval of 10 minutes.
