This pull request reduces the default TTL for FreeIPA-related DNS records from 3600 to 60.
💭 Motivation and context
It makes sense to reduce the default TTL to 60, since I intend to eventually add code to automatically update FreeIPA DNS records depending on the status of health checks. I am making this change now so that there is one less step I have to do when I upgrade the FreeIPA cluster, and also so I don't have to wait an hour (for the previous default TTL of 3600 to time out) before making changes.
AWS itself sets a TTL of 60 for most of their records to allow them to be updated at will without causing anything more than a very temporary glitch.
