Add new parameter to define ip address for storage networks

A new parameter storage_adapter_ip_info is added to allocate static ip address for storage network.

A sample definition could be

storage_adapter_ip_info = {
  storage_network_a = [{
    physicalNode = "HostA"
    ipv4Address = "192.168.200.10"
    subnetMask = "255.255.255.0"
  }, {
    physicalNode = "HostB"
    ipv4Address = "192.168.200.11"
    subnetMask = "255.255.255.0"
  }]
  storage_network_b = [{
    physicalNode = "HostA"
    ipv4Address = "192.168.201.10"
    subnetMask = "255.255.255.0"
  }, {
    physicalNode = "HostB"
    ipv4Address = "192.168.201.11"
    subnetMask = "255.255.255.0"
  }]
}
