* Fixed a bug where, in rare cases, $anvil->hostname() would call 'hostnamectl' and get a dbus error during shutdown, which would then cause the hostname to be changed to the error in the database. * Fixed a bug in Cluster->boot_server() where it would never verify that a server has started successfully. * Updated Database->get_ip_addresses() to store the IPs we manage in 'ip_addresses::<ip_address_address>::X'. * Updated ocf:alteeve:server to work from command line calls, though more testing is still needed. * Started work on 'anvil-rename-server', but haven't gotten far with it yet.
