Misalignment with extra-dhcp-options between neutronclient & openstackclient

[Eduardo Olivares]

The SetPort class from the openstack client does not support --extra-dhcp-option [1]
(overcloud) $ openstack port set --extra-dhcp-option name=mtu,value=1700,ip-version=4 port-test-202
usage: openstack port set [-h] [--description <description>]
                          [--device <device-id>] [--mac-address <mac-address>]
                          [--device-owner <device-owner>]
                          [--vnic-type <vnic-type>] [--host <host-id>]
                          [--dns-domain dns-domain] [--dns-name <dns-name>]
                          [--enable | --disable] [--name <name>]
                          [--fixed-ip subnet=<subnet>,ip-address=<ip-address>]
                          [--no-fixed-ip]
                          [--binding-profile <binding-profile>]
                          [--no-binding-profile] [--qos-policy <qos-policy>]
                          [--security-group <security-group>]
                          [--no-security-group]
                          [--enable-port-security | --disable-port-security]
                          [--allowed-address ip-address=<ip-address>[,mac-address=<mac-address>]]
                          [--no-allowed-address]
                          [--data-plane-status <status>] [--tag <tag>]
                          [--no-tag]
                          <port>
openstack port set: error: unrecognized arguments: --extra-dhcp-option port-test-202

The UpdatePort class from the neutron client supports --extra-dhcp-opt [2]
This is aligned with the neutron API [3]
(overcloud) $ neutron port-update port-test-202 --extra-dhcp-opt opt_name=mtu,opt_value=1750,ip_version=4
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
Updated port: port-test-202
(overcloud) $ neutron port-show port-test-202 | grep mtu
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.

This seems for me like lack of feature in the openstackclient. OSC uses storyboard to track issues. I opened bug in storyboard https://storyboard.openstack.org/#!/story/2009095 and I'm closing this one here.
