Flux: List series like measurements or cardinality

[Nick135]

Instead of calculate the cardinality it would be helpful to get all series to see if there is any option to optimize cardinality.

Proposal:
import "influxdata/influxdb/schema"
schema.series(bucket: "example-bucket")

Current behavior:
List all measurements, keys, tags and find all unique combinations (series).
Same as influxdb.cardinality(), but this functions returns only the count and not the name of the series.

Desired behavior:
List series

Alternatives considered:
write complicated query

Use case:
Very helpful to optimize cardinality vs. query performance
