  - Bugfix: Dovetail CI failed with Permission denied

    JIRA: DOVETAIL-451

    1. Dovetail CI jobs failed because of Permission denied.
    2. The directory ${WORKSPACE}/cvp/pre_config is created with sudo privilege,
       so fetch_os_creds without sudo got Permission denied.
    3. Remove the sudo when create directory ${WORKSPACE}/cvp/pre_config.
