[libvirt] [RFC PATCHv2 4/4] storage: Change hardcoded QEMU connection to use config driver

[Adam Walters]

This utilizes the new config driver I am submitting to resolve the
hardcoded QEMU connection string in the storage driver. With this, the
storage driver no longer has a circular dependency with QEMU. Without
this patch, when libvirtd is restarted, QEMU requires storage (when
domains are using storage pool backings), and storage requires QEMU (for
access to secrets). This causes issues during libvirtd startup.
