Revert to dual-homing with LACP for all hosts

Browse Source 
- All hosts now dual-homed to MLAG pairs using LACP bonding
- host1: connects to leaf1 (eth1) and leaf2 (eth2) - VLAN 40
- host2: connects to leaf3 (eth1) and leaf4 (eth2) - VLAN 34  
- host3: connects to leaf5 (eth1) and leaf6 (eth2) - VLAN 40
- host4: connects to leaf7 (eth1) and leaf8 (eth2) - VLAN 78
- Each host creates bond0 with LACP (mode 802.3ad)
- Proper MAC address assignment per host
