Use CML_TOKEN instead of REPO_TOKEN to

• avoid potential namespace clashes
• better reflect that it could be a project token, org token, bot token, encoded username & password, etc
• better reflect that it's mostly used to launch runners and also is used by runners

jest.it.each reduces the boilerplate test code and improves the readability and maintainability.
Currently config, tools and coverage tests use jest.it.each. The same can be done for utils, extensions and install tests.

Describe the bug
When scaling runners based on TotalNumberOfQueuedAndInProgressWorkflowRuns it seems that the maximum number of possible runners are currently 60.

Having testet with a workflow with 170 jobs (created by matrix), we only reached 50 runners.

We think the issue is related to missing pagination handling of the ListWorkflowJobs api here: https://github.com/actions-runner-co
