Add setting for disabling console logging

This commit adds an explicit setting for disabling console logging,
instead only writing to the main application log file. The setting name
chosen sets up a pattern for future logging configuration of files,
using the `logging.` prefix, followed by the log, and then the log
specific setting, in this case whether it is enabled.
