ACK for the idea

Just a comment:

Regarding to Ding Xiao patches, he added the upload function to the add 
template UI
But it only upload the image to Kimchi server and does not create a 
template from the uploaded ISO
If we will keep it on add template UI, we must do the whole process: 
upload the ISO and also create a template from this ISO file.
