According [https://code.djangoproject.com/ticket/29641] and
[https://code.djangoproject.com/ticket/29547] add support of conditional
unique constraint.
Postgresql and sqlite support it as unique index: `CREATE UNIQUE INDEX ...
WHERE condition`, for unsupported databases this constraint will not be
applied at all.
`unique_together` can be marked as deprecated in future as
`index_together` is.
