[SYNTH-16108] Show error stack trace and cause

[Drarig29]

What and why?

Before:

$ yarn launch synthetics run-tests -s 'test:('

 ERROR: unable to obtain test configurations with search query 
Request failed with status code 400

After:

$ yarn launch synthetics run-tests -s 'test:('

 ERROR: unable to obtain test configurations 
CriticalError: Failed to search tests with query: query on https://api.datadoghq.com/api/v1/synthetics/tests/search returned: "Make sure there is no missing parentheses"

  }
}

How?

For each error that we catch and want to re-throw, we now attach it as a cause on the new error.

Review checklist

• [x] Feature or bugfix MUST have appropriate tests (unit, integration)
