Provide a mechanism for specifying settings that is not based on the filesystem #19
Description
In some scenarios, settings such as logging and dev errors need to be enabled/disabled but updating the file system is not an option. For example, the app might be running in Azure WebSites as a site extension, which means the files are on the disk of the worker and are readonly. It would be ideal if the various iisnode settings could also be set via environment variables or some other mechanism that would work in this scenario.
