test_driver: Implement virDomainGetIOThreadInfo

Browse Source 
If we use test driver on different machines, and use 0 as bitmap_size
for virDomainDriverGetIOThreadsConfig(), we would get different results for
the `CPU Affinity`, because it's depending on the host CPU's bitmap. In
order to get a stable result for testing, use result of
virDomainDefGetVcpus() as bitmap_size instead.
