Test VM memory limits with maximum RAM and heavy workload

[OhmSpectator]

We need to create a test that runs a VM with the maximum available RAM for the system and performs a heavy storage and network workload within the VM. The purpose of this test is to validate that our memory overhead estimations and the memory limits set for the VM are accurate and stable under maximum resource utilization.

For example, for a device with 4Gb of RAM, we know that we can run a VM with 2.1GB of RAM, as the rest goes to the EVE system itself and the VMM overhead. But we need to check these estimations.

We can implement it in any suitable way and try to integrate it later.
