The option can only take integer values >= 0, since negative
TTL is meaningless and is expected to fail the query when used
with `USING TTL` clause.
It's better to fail early on `CREATE TABLE` and `ALTER TABLE`
statement with a descriptive message rather than catch the
error during the first lwt `INSERT` or `UPDATE` while trying
to insert to system.paxos table with the desired TTL.
