Update SBG e2e workflow to work across venues

[LucaCinquini]

Retrieve all dependent parameters from SSM or Airflow environment so that the DAG can run across all venues. Includes adding tests for the MCP test and prod venues.

This should involve replacing the SSM key for the primary data bucket:

UNITY_OUTPUT_DATA_BUCKET = "/unity/ds/data/bucket/primary-data-bucket"

with a new expression that includes the venue and deployment - for which the values are retrieved from the AIRFLOW env variables.

This task include updating the nightly test so they can work for unity-venue-dev, unity-venue-test and unity-venue-prod.

Chatted with Galen and decided to go with this format, for now:
UNITY_OUTPUT_DATA_BUCKET = "/unity/ds/data/bucket/{deployment_name}/{venue}-{counter}/primary-data-bucket"

As an example, "/unity/ds/data/bucket/luca/test-1/primary-data-bucket"

Does that make sense based on previous conversations y'all have had?

[LucaCinquini]

Sure, let's do that ...
