Add _get_fake_client to ironic-inspector actions
Add _get_fake_client to ironic-inspector actions

When populating the ironic-inspector actions, the client code tries
to get a proper version (since none was given). And thus, in that
code it may fail if inspector is not listening on localhost (which is
what it tries to access by default). By setting the version in the
_get_fake_client call, we avoid this call.
