[PATCH 5/5] KVM test: kvm_vm: Allow NIC MACs to be defined on config file

[Lucas Meneghel Rodrigues <lmr@redhat.com>]

In order to allow the multi-host migration test to start
VMs with the same MAC address, allow nic addresses to
be defined on the config file, such as:

nic_mac_nic1 = AA:BB:CC:DD:EE

This way we can generate a MAC on the server control file
and distribute this to the new VMs that are going to be
created.
