Our interval template started life as `range`, and was supported wrapping to follow Cassandra's convention of wrapping around the maximum token.
We later recognized that an interval type should usually be non-wrapping and split it into wrapping_range and nonwrapping_range, with `range` aliasing wrapping_range to preserve compatibility.
Even later, we realized the name was already taken by C++ ranges and so renamed it to `interval`. Given that intervals are usually non-wrapping, the default `interval` type is non-wrapping.
We can now simplify it further, recognizing that everyone assumes that an interval is non-wrapping and so doesn't need the nonwrapping_interval_designation. We just rename nonwrapping_interval to `interval` and remove the type alias.
