[nosdn-noha] Meet EPA testcases requirements (NUMA)

Install in a local directory a newer version of virt-manager
to workaround obsolete Ubuntu versions lacking --cpu cellN.* support.

This change only affects CPU cfg of virtual compute nodes in
nosdn-nofeature-noha scenarios with:
- set default cpu_topology to dual socket (2 cores, 2 sockets,
  2 threads);
- bump default RAM to 16GB;
- define 2 NUMA cells, each with half the resources;

To keep the old behavior available (single socket), a new deploy
argument has been added (`-m`). The RAM change is not configurable
via deploy args.

NOTE: The CPU topology for virtual nodes should later be read from
PDF instead of hardcoding it on a per-scenario basis in the installer.

NOTE: Default 'ram' unit is MiB, while cellN.memory default unit is
'KiB'.
