for #1817 # Details This PR gives Fleet servers the ability to connect to RDS MySQL and Elasticache Redis via AWS [Identity and Access Management (IAM)](https://aws.amazon.com/iam/). It is based almost entirely on the work of @titanous, branched from his [original pull request](https://github.com/fleetdm/fleet/pull/31075). The main differences between his branch and this are: 1. Removal of auto-detection of AWS region (and cache name for Elasticache) in favor of specifying these values in configuration. The auto-detection is admittedly handy but parsing AWS host URLs is not considered a best practice. 2. Relying on the existence of these new configs to determine whether or not to connect via IAM. This sidesteps a thorny issue of whether to try an IAM-based Elasticache connection when a password is not supplied, since this is technically a valid setup. # Checklist for submitter If some of the following don't apply, delete the relevant line. - [X] Changes file added for user-visible changes in `changes/`, `orbit/changes/` or `ee/fleetd-chrome/changes`.
