Currently, database instances and clusters have different behaviors for
removal policies and deletion protection. This fix standardizes the behavior
and logical code paths so RDS behaves consistently.

The new logic is that we will only set deletionProtection if the RemovalPolicy
has been set to RETAIN. Otherwise (with SNAPSHOT or DELETE), deletion protection
will be disabled (by default).

BREAKING CHANGE: Cluster now has deletionProtection enabled if its removal policy is RETAIN

  • rds: Instance now has deletionProtection enabled by default only if its removal policy is RETAIN

Looks great, but we absolutely need to mark this with BREAKING CHANGES, and with the multiple breaking changes format in fact.

Maybe something like this?

BREAKING CHANGE: Cluster now has default deletionProtection enabled if its removal policy is `RETAIN`
* **rds**: Instance now has deletionProtection enabled by default only if its removal policy is `RETAIN`
