[Why] Nodes need to communicate with each other when testing cluster jobs. After adding 2 fileds: 'direct_macs' and 'direct_ips', can bind ips to macs.

[HowTo] When you test a cluster job, need to config cluster file correctly. Below is the template:

<hostname>:
  roles: [ <"server">, ... ]
  macs: [ <mac>, ... ]
  ips: [ <ip>, ... ]

<hostname>:
  roles: [ <"client">, ... ]
  macs: [ <mac>, ... ]
  ips: [ <ip>, ... ]

For 'ips': 1) should be the intranet IP

Does the ips is come from 'ifconfig'? when our physical machine restart the intranet IP maybe randsom allocation? so should we may consider to bind a fixed ip for physical machine.

Thanks, Zhangyu

        2) all ips in cluster file should be in the same network segment
    3) subnet mask is 24.

[InFuture] Set default ips when there's no ips in cluster file or only one host has ips.
