[baremetal] MaaS: Fix DHCP dynamic reserved range

- patch MaaS to default to `DHCP` instead of `AUTO` for physical
  PXE interfaces (all IPs will be handed out by MaaS DHCP *inside* the
  defined dynamic DHCP IP range);
- reduce range to silence bogus MaaS warning about address exhaustion;
- regenerate pod_config.yml.example to reflect the changes;
- drop `opnfv_infra_maas_pxe_address` (duplicate of
  `opnfv_infra_maas_node01_deploy_address`);
- add `opnfv_infra_config_pxe_address` for future usage;
- while at it, fix missing patch copyright;

+Subject: [PATCH] maas: region: interface: default mode DHCP
+
+Switch MaaS interface mode default from AUTO to DHCP.
+This way, MaaS will not statically assign IPs *outside* the dynamic
+reserved range, but instead DHCP will assign them *inside* the range.
+
+One alternative would be to handle this via API calls, for each
+node's PXE physical interface, but that overcomplicates things.
