Summary: Adds a new configuration variable to control the verbosity of MCCL Scuba logging. This enables operators to filter out lower-priority logs and reduce noise in Scuba tables, improving observability by focusing on the most relevant events (critical errors, high-priority events, etc.) while reducing storage costs and query complexity.

Also making  MCCL_SCUBA_ENABLED=true by default so that we always have log for any job.
