Subject: [PATCH] Remove the restriction that SR must be FS based SR

We can support non-FS based SR with the supporting on VDI streaming
feature. And VDI steaming will be the default image handler. So
this commit is to change the installation script to allow no-FS
SR types. For the VDI streaming feature, please check the depends-on.
