Currently, if '--public' is specified, an image is created but
it is not marked as public:
$ glance image-create --public --name minus-minus-public --disk-format raw \
--container-format bare < /etc/fstab
+------------------+--------------------------------------+
| Property | Value |
+------------------+--------------------------------------+
.
.
.
| is_public | False |
.
.
.
+------------------+--------------------------------------+
This is inconsistent.
'--public' has been deprecated for some time, and has
been removed from devstack (https://review.openstack.org/#/c/39323/),
so we can finally get rid of it.
We now raise the standard error for unsupported arguments.
