Use openSUSE 15.0 as default, which is the latest released stable
openSUSE release. Switch to https for accessing download.o.org
as encrypted transfers should be used by default.
Remove leftovers for definitely unmaintained openSUSE 13.x images
and split into old/new leap style versioning scheme for clarity.

In preparation for promoting the openSUSE jobs to voting ones we should
use the OpenStack mirrors. As such, the opensuse elements are modified
to make use of the DIB_DISTRIBUTION_MIRROR variable which is normally
exported by the openstack-ci-mirrors element.

Currently openSUSE 42.3 has entered feature freeze mode
so it is a good point in time to verify that 42.3 builds
are working successfully. Also test opensuse-minimal for
platforms that support it (need working zypper package)
