Process-wide loguru configuration. Import `logger` from here in every
module instead of instantiating new loggers.

Log level is controlled via `SPARK_EXECUTOR_LOG_LEVEL` (see common/config.py):
  DEBUG  - default; full verbosity
  INFO   - quieter; recommended for production

Levels used in this project:
  DEBUG  - entry/exit of public tools, subprocess commands, file I/O paths
  INFO   - business events (job submitted, status changed, connection saved)
  WARNING - recoverable problems (transient YARN issues, retry-able)
  ERROR  - raised exceptions (caller will see the traceback)
