At the Pike PTG, an issue was brought up regarding the use of an old API
version in the ironic OpenStack CLI plugin. [0]
It was suggested that we begin printing a warning whenever the default
OSC API version is used and later default to using the latest API
version when --os-baremetal-api-version is unspecified.
This patch adds the warning discussed above.
