Teuthology uses deprecated openstack ip <subcommands> - incompatible with newer OpenStack CLI

[deepssin]

Summary
The teuthology-openstack tool currently invokes several OpenStack CLI commands under the legacy format:

openstack ip <subcommand>

However, this command structure is no longer supported in recent versions of openstack. PS - openstack.org- floating ip

This results in runtime errors like:

openstack: 'ip floating list' is not an openstack command. See 'openstack --help'.

Impact

• Test jobs fail at the VM provisioning stage
• teuthology-openstack exits prematurely without creating VMs

Example Problematic Command:
Current (broken):

openstack ip floating list -f json

Modern equivalent:

openstack floating ip list -f json
