Apply DHCP option to network

[juanituarte]

Issue description

I want to add a DHCP option using the Python library but I couldn't figure it out.
Could you give me some guidance?

Example code

from infoblox_client_master.infoblox_client.objects import DhcpOption
from infoblox_client_master.infoblox_client.connector import Connector
from infoblox_client_master.infoblox_client.object_manager import InfobloxObjectManager

from credentials import credentials
from urllib3 import disable_warnings
disable_warnings()

ib_conn = Connector(
    dict(host='xxxx', 
    wapi_version='2.11.2',
    iba_dns_view='default', 
    iba_network_view='default', 
    iba_verify_ssl=False, 
    **credentials["lab"])
    )

dhcp_option = DhcpOption()
dhcp_option.name = "option"
dhcp_option.num = 240
dhcp_option.space = "ztp_fortinet"
dhcp_option.type = "IPv4 Address"


manager = InfobloxObjectManager(ib_conn)

subnet = manager.get_network('default', "172.23.125.0/27")
subnet.dhcp_option = [dhcp_option]
subnet.update()
