Subject: [PATCH] Revert "[baremetal] Retire mas01 NAT"

Bring back public internet access to all cluster nodes via NAT
on mas01 node, required for NTP syncing.

NOTE: Both mcpcontrol and PXE/admin networks are currently
hard wired to using /24 netmask, so we leverage that in pxe_nat.sls.

JIRA: FUEL-348

This reverts commit 9a6e655e0b851ff6e449027c01ac1a66188b0064.
