python-openstackclient for ironic-discoverd fails like:
$ openstack baremetal introspection status <uuid>
ERROR: openstack 'utf8' codec can't decode byte 0xa5 in position 89:
invalid start byte
When set "DISCOVERD_URL" environment value as http://<my_ip>:5050,
this error doesn't occur.
So that, the reason of this error is using localhost as default url.
This patch set fix the default url to host's URL.
