domain: Introduce virDomainIOThreadsPin{Add|Del}
https://bugzilla.redhat.com/show_bug.cgi?id=1135491 More or less a virtual copy of the existing virDomainVcpuPin{Add|Del} API's. NB: The IOThreads implementation "reused" the virDomainVcpuPinDefPtr since it provided everything necessary - an "id" and a "map" for each thread id configured.
