Remove impersonation lifetime. (#882)

* Remove impersonation lifetime. Per #769 , we shouldn't need to set the lifetime of an impersonated token. In some edge cases, attempting to set it to the job execution timeout (> 300 seconds) can result in authentication failures, even though the job will complete successfully and authentication creds will be correctly refreshed. * Changie data. --------- Co-authored-by: Doug Beatty <[email protected]> Co-authored-by: Mike Alfare <[email protected]>
