IO: Add the if-exists query parameter by updating to influxio 0.4.0

[amotl]

Problem

Because the InfluxDB I/O subsystem, implementing ctk load table influxdb2://..., always replaced the target table, it could have been considered as "just a toy". Thanks to that discovery by @wierdvanderhaar, we have been able to improve it.

Solution

The improvement follows the semantics of the to_sql() implementation of pandas/Dask, and now takes a new if-exists URL query parameter into consideration, forwarding the possible values {fail,replace,append} to the corresponding implementation.
