Refactor failables

This is a breaking change as big part of current failable_deliverables
options will be ignored.

There is no change for buildinstall and creatiso phase.

Failability for artifacts in other phases is now configured per
artifact. It already works correctly for ostree and ostree_installer
phases (even per-arch). For OSBS phase there is currently only a binary
switch as it does not handle multiple arches yet. When it gains that
support, the option should contain list of non-blocking architectures.

For live images, live media and image build phases each config block can
configure list of failable arches. If the list is not empty, it can
fail. Once we have a way to fail only some arches, the config will not
need to change.
