[pve-devel] [PATCH pve-flutter-frontend v3] node overview: add power settings menu

[Dominik Csapak]

similar to how it works for qemu, but add a confirmation dialog
so one does not accidentally shutdown or reboot a node.

Signed-off-by: Dominik Csapak <d.csapak@proxmox.com>

changes from v2:
* reordered and renamed yes/no on the confirmation dialog
* slightly adapted the confirmation text
