DBT-based example project

[istvan-fodor]

Once the Snowflake deployment issue is completed , we should create an example project that

1. Reads a file from S3 and stores it record by record in Snowflake
2. Processes the file in DBT and creates a data-mart

Example data-file will be provided outside of this issue.

@tfoldi , can you help the team who will be working on this by showing them how to include example code in the HVR deployment?
