Log level configuration

[gadkadosh]

I'm very new to packer, and was trying to debug some behavior I wasn't sure about (and still am not...)
Since there's a nice logger builtin I naturally wanted to use it, but quickly realized it doesn't respect the log = { level } configuration. It stays on the default "warn" setting.
I could be totally wrong here, as I'm new to both packer and Lua, and still learning and trying to understand how it works.
However, it seems to me that since #331, log configuration takes place in 'startup' before 'init', and thus doesn't respect the log configuration.
If needed, I can provide more information, but for now it seems pretty straight forward so I'm posting this as is.
