Allow logging to be controlled through `config` command

As a continuation of #852, allow changing the default sizes and number of files through configuration settings in choco. This was pushed as configurations is not available when setting up logging, so they would need to be adjusted as soon as the configuration is available.

This was originally requested by @DarwinJS

Start by reading the related issue #852 and the choco `config` command, then trace how logging is initialized before configuration is available. Identify how default log sizes and file counts are currently set. Done means those defaults can be changed through configuration settings and are applied when logging is set up.
