Add --node to 'openstack baremetal port list'

This adds an optional '--node' (name or UUID of a node) to the
'openstack baremetal port list' command. It provides the ability
to get a list of ports of a specified node.

The existing release note covers this:
releasenotes/notes/osc-plugin-7769f5bef627654c.yaml.
