setLogLevel function on the cli package

[danielpeintner]

However, it seems that you didn't update the setLogLevel function on the cli package. We should probably talk about it in an issue.

Yeah, I was a bit unsure about this part of the cli package, as it seemed to me as if the log level should cause messages to be printed out for the user independently of their knowledge about the debug module/environment variables. If we switched to using debug here as well, the setLogLevel function/action could become obsolete. As this seems to require a bit more discussion, opening an issue is definitely a good idea :)
