When we show a volume type object we can see:
openstack volume type show test

| description | None |

There are two properties named "is_public" and "os-volume- type-access: is_public" ,
They are the same things, we just need one. We can remove the "os-volume- type-access: is_public"
and leave only the "is_public" property
