Work includes:

• Fix to listen address toml line

Testing performed:

• Created a runner under a birthright cloud allocation at CADES cloud using examples directory
• Used sample terraform.tfvars.sample to make a terraform.tfvars file with runner_tokens set to a list of a single token for this repository
• Modified the examples/main.tf to point to locally development source = ../modules/ornl-cloud-gitlab-runners
• Ran terraform init; terraform apply in examples to create the runner
• ✅ Checked that it was correctly registered to this repository using the runner token
• ✅ SSH'ed into runner and ran docker-compose --version to ensure it was v1.29.2 (the default)
• ✅ Checked metrics were accessible via http://<runner IP address>:9252/metrics
