  - Pass jenkins variables to daisy deploy script

    JIRA: DAISY-42

    Now the daisy deploy script is executed with sudo. In [1], daisy
    deploy job needs to check INSTALLER_IP when it generates the
    configuration by the POD Descriptor File. So -E option of sudo
    is necessary to pass the jenkins variables.
