drop influxdb python dependency

We haven't used influxdb in a long time, remove the dead code and unused
dependency.

Some code in experiments/ and kettle/ relied on 'requests' being
transitively being pulled in by influxdb, so specify that explicitly.

 ## Query structure
 
 The `query` is written in `Standard SQL` which is really [BigQuery Standard SQL](https://cloud.google.com/bigquery/docs/reference/standard-sql/query-syntax) that allows for working with arrays/repeated fields. Each sub-query, from the most indented out, will build a subtable that the outer query runs against. Any one of the sub query blocks can be run independently from the BigQuery console or optionally added to a test query config and run via the same `bigquery.py` line above.
