Specify what presence of an image means

No description provided.

Note: This has to be debated in SIG Std/Cert, particularly the case of visibility=community.
I presume @berendt will want this, but I'm not sure this finds consensus.

@mbuechse Could you please elaborate/confirm that this change only aligns the canonical texts with the existing compliance checks. Since I see no diff in Tests I assume so, but I think it would be good to have it explicitly spelled out.

[berendt]

Visibility of community < public. Fine for me the add this. I don't like the public visibility and prefer community over public.

@toothstone I can confirm that:

standards/Tests/iaas/openstack_test.py

Line 66 in 514377b

c.add_function('images', lambda c: [img for img in c.conn.list_images(show_all=True) if img.visibility in ('public', 'community')])

However, in my mind, it's more important that the standard makes sense. This is v2, which is still a draft, so we can and should discuss in the SIG what makes most sense.
