Per-thread variables for parallel jobs

[PhilShaughnes]

Is there a way to provide a variable that is unique or specified for each thread?
For example, say I am testing some jobs that require locking behavior: https://url/job/namespace
Where:

• each namespace is locked while the job is running
• subsequent requests will just wait to try and get a lock

When running multiple jobs, this means I can't actually run tests against multiple namespaces simultaneously(e.g. namespace-one, namespace-two, namespace-three, etc) without wrapping hurl in parallel or something similar.

Ideally each file could have something like POST https://url/job/test_{{SUFFIX}}
and then I could specify --job-variables SUFFIX="red,green,blue" or something (indicates run a max of 3 jobs)?
