major steps (copying from formrecognizer):

• Indicate in your tests.yml that you want your samples to run by setting parameter TestSamples: true . Example:
  https://github.com/Azure/azure-sdk-for-python/blob/master/sdk/formrecognizer/tests.yml#L9
• Add any environment variables used in your samples to your tests.yml and update them in the keyvault/devops variable group if needed. Example: https://github.com/Azure/azure-sdk-for-python/blob/master/sdk/formrecognizer/tests.yml#L54-L71
• Run your live test pipeline. Samples will run as a separate step after tests complete.

for eventhub:

• most samples are running forever because of the push mode
  • either tweak them not to run forever
  • or exclude the sample via setting IGNORED_SAMPLES inside scripts/devops_tasks/test_run_samples.py
    • see PR: https://github.com/Azure/azure-sdk-for-python/pull/16033/files

IGNORED_SAMPLES = {
    "azure-eventhub": [
        "<sample not to be run>.py",

(add comment on why we need to ignore some of the samples)
