- route53_health_check - add support for another ``type`` choice called ``CALCULATED`` (https://github.com/ansible-collections/amazon.aws/pull/1631).
- route53_health_check - add support for a string list parameter called ``child_health_checks`` to specify health checks that must be healthy for the calculated health check (https://github.com/ansible-collections/amazon.aws/pull/1631).
- route53_health_check - add support for an integer parameter called ``health_threshold`` to specify the minimum number of healthy child health checks that must be healthy for the calculated health check (https://github.com/ansible-collections/amazon.aws/pull/1631).
