Proxmox supports tags, so class Proxmox supports tags, too.
It is possible to show and change tags in config and `e status` prints
tags.
The new command `e ct volume_move NAMEORID DISK POOL` "moves" the disk
of a CT to an other RBD-pool. It only supports RBD, yet.
It uses XFS on the new device.
The CT must be stopped on the same machine, you are calling the command.
The class PVE::Output helps to print status. Supports info, failed and
progress (with a spinner). Monitoring tasks used a custom spinner,
which is now part of the new PVE::Output.
The status of CTs/VMs/Nodes are symbols only. Strings shouldn't be used
anymore.
The interactive shell provides tab-completion for LXC-/VM-/Node-names and IDs.
CLI provides storage-management, including listing storages and there
contents.
Also added: Listing and downloading of APLs to storages.
