OVN: Add support for DHCP option 150 - TFTP server address
OpenStack Ironic relies on a few DHCP options [0] that were not
supported in OVN yet. This patch is adding the last one which is the
option 150 (TFTP server address, RFC5859 [1]).
Note that this option is Cisco proprietary, the IEEE standard that
matches with this requirement is Option 66. The difference is that 150
allows to multiple IPs to be specified and 66 only allows one.
