When reloading we need to disable debug output when the debug plugin is removed from the config file. Add a `Clear` function to pkg/log and use it in the server server. Add test case in pkg/log, for actuall check I manually checked the output by sprinkling some debug statements in the startup and checking with sending SIGUSR1. Also clear up the comments in pkg/log to remove the text about time stamping. Fixes: #3035 Signed-off-by: Miek Gieben <miek@miek.nl>
