Move scoofy data generation into this repo

[jankatins]

Currently the scoofy data generation happens outside of this project (basically a lambda + a s3 bucket) and needs a cross account setup to copy data into the data lake. It makes sense to simply add the s3 data directly into the raw data lake bucket, similar to what currently the copy job does. This would also mirror what we expect to happen in the cdc-from-RDBMS case (#7).

Tasks:

• Remove the copy job
• Add the data generation lambda to put data into the same place

DoD:

• Data generation happens here

(see also #21 for adjusting the current setup in multiple ways)
