Retrieve a paginator class appropriate for the +key+ in Redis.
 +key+ must be one of +list+ or +zset+, otherwise an exception
 will be raised.

 @params key [String] Redis key
 @params options [Hash] Options to be passed to the individual paginator class.

 @return Returns either a +RedisPagination::Paginator::ListPaginator+ or
   a +RedisPagination::Paginator::SortedSetPaginator+ depending on the
   type of +key+.
