[ETL-677] Add bootstrap script for Snowflake Parquet tables

[philerooski]

This script will load data into each of our Parquet tables one by one. It's expected to take a few hours to run on an xsmall warehouse.

You can test this script yourself by creating a testing branch from this branch, pushing your new branch (triggering the Snowflake deployment), copying dev Parquet data from the main namespace over to your namespace in S3 s3://recover-dev-processed-data/my_test_branch/parquet/, and then using the Snowflake CLI to invoke this script:

snow sql -f snowflake/scripts/copy_into_each_parquet_table.sql -D "database_name=recover_my_test_branch" -D "schema_name=parquet" 

It's important to note that the current behavior of this script and the stored procedure which it invokes is meant to fulfill the needs of doing a one-time initial load of our Parquet data for demonstration/sandbox purposes. Because our Parquet datasets are overwritten in S3, running this script on different days would load duplicate records – although we wouldn't have a way to differentiate them (e.g., there is no field indicating the Glue workflow which produced them or any other indicator of their ordinality).
