Move `virsh pool-refresh`

The `pool-refresh` command is used to ask libvirt to rescan the content of a volume pool.
This is used to make `libvirt` take into account volumes that were created outside of livirt control
i.e.: not with a `virsh` command.

`pool-refresh` is useless after a `pool-create` as the content is scanned at creation.
`pool-refresh` is mandatory after having created files inside an existing pool.
