make bigsampler bq output partition configurable

adds a new arg to BigSampler called bigqueryPartitioning, defaults to "DAY", which should maintain the same behavior as before. Users can pass in "DAY|HOUR|MONTH|YEAR", as well as NULL if no table partitioning is desired.

Making this change so that Ratatool works better with Spotify's internal Luigi BigQuery tasks, which use table sharding as partitioning, and when ratatool sets the partitioning to ingestion day, it causes problems with retention.

Tested by outputting this table via this workflow:

the 43ea5c916cd5a85623bf0de598da15982c29d8952dbf63a068d10e5b56466e61 docker image is using my local ratatool PR's code via sbt publishM2

the linked table has to partitioning and uses the sharding generated by the BigQueryTarget in Luigi

here is another table that is using the --bigquery-partitioning arg to set the partitioning to "MONTH".
