This change is introduced in a backwards compatible change. To use the new functionality withConnectionPoolSettingsBuilderFromAttributeMap should be used. Check the unit tests for examples

@jtjeferreira when you get this working, would you mind also doing a PR for https://github.com/apache/pekko-connectors which has a Pekko version of this code (in a module)?

For sure. I thought the pekko fork was in https://github.com/pjfanning/aws-spi-pekko-http/ ...

We've brought it into Apache Pekko Connectors 1.1. I will maintain https://github.com/pjfanning/aws-spi-pekko-http/ for bug fixes because Apache Pekko Connectors 1.0 still use it but there is probably not much point adding enhancements to my fork. In theory, the Apache Pekko Connectors 1.1 copy of this lib should work with Pekko Connectors 1.0 anyway.
