Automatically mount drives when running storage tests

When running disk/storage_device_* jobs, if the drive is not mounted, we now check if it can be mounted (i.e. if it has a partition) and if possible we mount it to a dedicated temporary location in order to perform the storage tests. LP: #1660386
