I prefer using an action rather than POST to collection itself, reasons:

     1. If upload share the same REST API with create volume, the model 
logic of create volume will be messed up. Since upload and create 
fulfill different tasks, we have reason to distinguish them.
     2. If in the future, we support create volume based on another 
storage volume, we may use identical parameters and API as this one. 
That will confuse user.
        So to make the REST API match its function, I prefer to use 
"POST upload".

I think upload and download can share same REST API.

As I have proposed to utilize libcurl, I think we can keep in line with 
protocols libcurl support.
Also qemu iso streaming uses libcurl, so if a user found an ISO useful 
when using iso streaming, he may want to download it with kimchi.
If we keep same protocol, same urls can be used.
