Improve logging

Some things that would improve logging:

• Reduce noise from Abort notifications by removing INFO level message
• Change "Closing runners" message to "Closing filter "
• Log (DEBUG) each filter's response (including filter name)
• Replace f-strings with deferred format strings, especially for DEBUG & INFO messages
  • Research use of bracketed format strings in logging
• Consider a Runner logger attribute to allow users to replace
  • useful for determining origin of messages with multiple runners
