Since create_hypertable() allows you to optionally specify a partitioning column, it makes sense to default to one partition when no column is specified and asking for the number of partitions when a column is specified and the number of partitions is not (instead of defaulting to one). This patch also changes the order and type of partitioning-related input arguments to create_hypertable() so that the number of partitions can easily be specified alongside the partitioning column and without type casting.
