When testing some interfaces, if you only care about path and do not care the data type or
compression type and other details, then use this function to create a timeseries quickly. It
returns a CreateTimeSeriesPlanImpl with data type of INT64, TSEncoding of PLAIN, compression
type of SNAPPY and without any tags or templates.
