Support for MAC address when VM count > 1 in AIAP

Current AIAP implementation has support for multiple VMs for
target/worker with an attribute "count".
But this is not supported for corresponding new MAC addresses.
The current implementation has mac address fixed for one
target node/one worker node.
This PS provide change in ansible playlist to handle
MAC addresses as list.
