`/query` endpoint: Describe the `series` schema in `/query` responses

[jstirnaman]

Issue description The API documentation for the v1.x compatibility endpoint lists several Array objects under the Series object that are not explained. For example the partial object: the customer is not seeing that key returned in responses but they need to know what (if anything) the field means in order to implement against it.

What product(s) and version(s) does this apply to?

• InfluxCloud 2.0

Link(s) to documentation that needs to be changed

• https://docs.influxdata.com/influxdb/cloud/api/v1-compatibility/#operation/PostQueryV1

What needs to be added or updated?

• object/field descriptions and any implementation details
  • expand the 200 response section then expand the series object
