Fix kayobe baremetal compute commands

Since adding support for Python 3, the following commands fail:

* kayobe baremetal compute inspect
* kayobe baremetal compute manage
* kayobe baremetal compute provide

There are two issues:

1. There is a missing /bin from the ansible_python_interpreter path used.

2. The stackhpc.os-ironic-nodes role fails with an undefined variable:

    name 'openstack_cloud_from_module' is not defined

This is fixed in the stackhpc.os-ironic-nodes role version 1.3.1.
