Now prov_mac_address is going to be dropped from bm_nodes table. This patch adjust api to the change. A user is expected to create a node without specifying prov_mac_address, then add an interface having the address to the node. However, for compatibility, a user still can specify prov_mac_address when create a node. In this case, an interface having prov_mac_address is automatically added to the node. In response body of create, index and show, "prov_mac_address" field no longer exists since they are showed as a member of "interfaces" fileld.
