  - Merge "Fix centos kickstart_done snippet"
  - Fix centos kickstart_done snippet

    Bug:
    CentOS-7-Minimal-1611-x86_64 image doesn't contain
    wget package and kickstart_done snippet use wget to
    call cobbler api to set netboot enable to false.
    This way if host installed centos which is not set
    to boot from disk will stuck in pxe loop

    Solution:
    Use curl instead of wget in kickstart_done
