Subject: [baremetal] Containerize MaaS

- replace mas01 VM with a Docker container;
- drop `mcpcontrol` virsh-managed network, including special handling
  previously required for it across all scripts;
- drop infrastructure VMs handling from scripts, the only VMs we still
  handle are cluster VMs for virtual and/or hybrid deployments;
- drop SSH server from mas01;
- stop running linux state on mas01, as all prerequisites are properly
  handled durin Docker build or via entrypoint.sh - for completeness,
  we still keep pillar data in sync with the actual contents of mas01
  configuration, so running the state manually would still work;
- make port 5240 available on the jumpserver for MaaS dashboard access;
- docs: update diagrams and text to reflect the new changes;
