Set IPV4 interfaces

If a gateway, netmask, or IP address of an IPV4 interface changes on
the page, when the user hits "Save changes" and confirms the popup,
delete the old IPV4 interface and create a new one with the new
values. After talking with Ratan, deleting then adding is the
the correct way to change IPV4 interfaces.
More information can be found in the network README up for review:
https://gerrit.openbmc-project.xyz/#/c/6872/

Tested: Changed IPV4 interface properties on a Witherspoon.
Also tested a Witherspoon in DHCP mode then moved over to a static
IP.
