Title: libvirt.tests: Fix some problems of storage_discard

*Always closing session after logining to vm.
*Change timeout to allow fstrim with large disks.
*Use a new vm for easy cleanup.

* For new version, the output will include human-readable format(Mib)
Force to use bytes to parse the fstrimmed size.
* Increase the timeout of fstrim because for large device(>1G),
it may take more time.
* Output the result of vgthin for debug.

*libvirt.tests: Fix attributes' error of channel.
