Use FreeBSD autoscaler for "stress" tests

The FreeBSD autoscaler has been configured to utilize the new "instance"
GitLab Runner executor to spawn "stress" test CI jobs on AWS EC2
dynamically. A shared GitLab Runner named "freebsd-instance-autoscaler"
has been set up in GitLab CI/CD to communicate with EC2, provisioning VM
instances on demand based on a FreeBSD 13 AMI image. This image is the
same as the one previously used for FreeBSD "stress" tests before the
implementation of autoscaling (specifically, the
"freebsd13-amd64-bind9stress.aws.lab.isc.org" GitLab Runner in CI/CD).
