The tickets #15310 and #16227 introduce a nice `availability` keywords
that answer to the question "Does Sage knows how to build a TD(k,n)"?
Using `Unknown` from `sage.misc.unknown` we can turn the question into "Do
we now mathematically how to build a TD(k,n)?" whose answer would be:
- `True` if Sage knows how to do it
- `Unknwon` if neither Sage nor mathematics can help
- `False` if we know mathematically that such construction does not exist
As the semantic changes, we will also turn the keyword `availability` into
`existence` (or maybe have both).
