[libvirt] [PATCH v2 1/4] test_driver: introduce domain-private data
vm-specific data can be used by APIs that need to preserve some state
between calls
Some of them are:
- FS-related APIs for remembering which mountpoints are frozen
- virDomainSetTime / virDomainGetTime for maintaining time information
- virDomainSetIOThreadParams for storing the I/O thread parameters
- virDomainManagedSaveDefineXML for internally storing the VM definition
