feat(outputs.influxdb_v2): Preserve custom query parameters on write

[glinton]

Summary

Preserves any custom query parameters used in URLs in the influxdb_v2 output plugin.

This also speeds up the write path by building the non-changing parts of the "writeURL" once while still allowing for tag (or otherwise) defined destination buckets.

Thanks for the nice speedup and feature @glinton! I do have one comment in the code. Furthermore, could you please rebase this PR on the latest master to make tests pass!?
