Using Influxdb 1.7.4, this

client = InfluxDBClient(HOST, database='test')
client.delete_series()

yields

influxdb.exceptions.InfluxDBClientError: 400: {"error":"error parsing query: found EOF, expected FROM, WHERE at line 1, char 13"}

Looks like either measurements or tags should be provided.

This is not explicit in the method documentation. Perhaps a note should be added in the docs, and an exception raised if no filter is passed.

Or if it is actually possible to delete all measurements at once in Influxdb, then I guess delete_series ought to be fixed.

Or am I missing something?
