Add per plugin logging to make it explicit what is logging, if you
include this package under the name clog (coredns log), you can do the
following:
log := clog.NewWithPlugin{whoami{}} // e.g.
And then just log.Info(...); these will then include the plugin ala:
[INFO] plugin/whoami: stuff
So we only need to init the logger and then just use it.
