[libvirt] [PATCH v3 1/7] qemu: Add defines for the news throttle options and modify the structure _virDomainBlockIoTuneInfo.

Add defines for the news options total_bytes_sec_max, write_bytes_sec_max, read_bytes_sec_max total_iops_sec_max, write_iops_sec_max, read_iops_sec_max, size_iops_sec. Modify the structure _virDomainBlockIoTuneInfo to support these options. Change the initialization of the variable expectedInfo in qemumonitorjsontest.c to avoid compiling problem. Allow libvirt to save the configuration.
