* Created the new anvil-manage-server-storage tool which will specifically handle managing a server's disks.
* Created DRBD->parse_resource() to pass a specific DRBD resource's XML data. * Fixed a bug in Get->available_resources() so that if the threads is lower than CPU cores, the cores are used as the total available to VMs. * Fixed bugs in Get->server_from_switch() where it just wasn't working properly. * Updated scan_drbd to not reset a resource's size to 0-bytes when a resource goes offline.
