Fix parquet default processor and clean up a bit (#480)

* - removed table_metadata from parquet, which is a problematic in terms of not being sent to channel [todo: rootcause]
- added fields to logs for easier debugging
- moved parquet periodic upload logic before looping structs.
- made parquet gap detector logic simpler.

* fix events

* fix token_v2 version tracking
