Why do we need this if it's coming from the message itself? I don't like that the node can report whatever it wants.

Because on the message we don't have the real sizes used on the VMs, like on volumes and on runtime and code. The idea of this PR is to show the real resources used by the VMs. Indeed the PR need tobe finished solving the TODO tasks, I have put on review just to check the format.

From our conversation earlier, the goal of this PR is unclear. Let's not merge it until its purpose is clarified.
