Add dedicated logger for management commands

[matthew-li]

Description

**** Please include a summary of the change and which issue is fixed. Please also include relevant motivation and context. List any dependencies that are required for this change. ****

• Added a coldfront.commands logger, to be used for management commands, that writes to the console and to a file in monolithic deployments, and only to the console in containerized deployments.
• Updated critical management commands to:
  • Use the new logger
  • Stop writing to stdout/stderr manually (handled by the logger)
  • Consolidate multi-line logs into one where appropriate
  • Remove unnecessary messaging
  • Add "DRY RUN: " prefixes to messages when in --dry_run mode.
• Configured structlog to process extra log data.
