Add JOB_ID environment variable to allow correlation between the job and the test run

[AAraKKe]

What does this PR do?

Adds JOB_ID environment variable that allows correlation between the test executed in a given job with the the job execution in Datadog.

Motivation

There is a limitation by which ddtrace does not have access to the run id of the job that is running the tests. Because of this, tests are properly correlated at a pipeline level but not at a job level. After asking the CI visibility team, adding an environment variable JOB_ID with that information, correlation can be achieved.

Review checklist (to be filled by reviewers)

• Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
• Add the qa/skip-qa label if the PR doesn't need to be tested during QA.
• If you need to backport this PR to another branch, you can add the backport/<branch-name> label to the PR and it will automatically open a backport PR once this one is merged
