The mainly changes are:
1) Update qemuMonitorGetBlockStatsInfo and it's children (Text/JSON)
functions to return the value of new latency fields.
2) Add new function qemuMonitorGetBlockStatsParamsNumber, which is
to count how many parameters the underlying QEMU supports.
3) Update virDomainBlockStats in src/qemu/qemu_driver.c to be
compatible with the changes by 1).
I'm not sure we should extend the existing set of function
used by GetBlockStats instead of creating new functions asking/looking
for the full set of values. On one hand it's good to share the code,
but on the other hand if this leads to more round-trip between
libvirtd and qemu I would rather keep them separate. I.e. we should
pay the extra cost only when asking for the extra data.
