Disable aws cli pager

[artkrz]

When using the following step:

- label: Deploy
    concurrency_group: "cicd-eval-deploy"
    concurrency: 1
    plugins:
      - ecs-deploy#v3.0.0:
          cluster: "cicd-eval"
          service: "cicd-eval-buildkite"
          task-family: "cicd-eval-buildkite"
          image: "xxx.dkr.ecr.us-west-2.amazonaws.com/cicd-eval:${BUILDKITE_BUILD_NUMBER}"

deployment stalls:

This is caused by paginated output of task definition json, to mitigate I've added:

[default]
cli_pager=

to ~/.aws/config of buildkite-agent user home but this should be addressed by adding --no-paginate to all AWS CLI commands.
