openstack的horizon的上傳映象流程
通過html的form表單上傳檔案
先上傳到horizon指定的臨時目錄，儲存起來
通過glance-api請求介面
實際上glance-api也是提供了一個上傳介面，由前面我們儲存的臨時目錄，上傳到glance-api的映象建立介面;
[root@node-8 images]# glance --debug image-create --name='test' --is-public=true --disk-format=iso --container-format=ovf < /root/Fedora-Live-XFCE-x86_64-19-1.iso

當我們確定映象已經成功後，將刪除dashboard的臨時儲存目錄的映象。
