Help info for floating IPs fails without credentials

[seanhandley]

Accessing the help information in the openstack tool should work whether you have credentials set or not i.e.

$ openstack help server list
usage: openstack server list [-h]
                             [-f {csv,html,json,json,table,value,yaml,yaml}]
                             ....

If you try to do the same for floating IPs you're met with the following error:

$ openstack help ip floating list
Missing parameter(s):
Set a username with --os-username, OS_USERNAME, or auth.username
Set an authentication URL, with --os-auth-url, OS_AUTH_URL or auth.auth_url

It seems some of the subcommands take a logic path that tries and fails to create a connection. Since all the help docs are hardcoded, this shouldn't happen.
