Correct plugin logging (#3185)

* The plugin logger should use verbosity level The log level is meant to be used only for log files. Signed-off-by: Kim Christensen <kimworking@gmail.com> * Correctly detect log level from plugin logs The constants used before was numbers, causing the writing to always fall back to writing as debug Signed-off-by: Kim Christensen <kimworking@gmail.com> * Correct the documentation Signed-off-by: Kim Christensen <kimworking@gmail.com> * Do not log information messages from the plugin infrastructure Signed-off-by: Kim Christensen <kimworking@gmail.com> --------- Signed-off-by: Kim Christensen <kimworking@gmail.com> Co-authored-by: schristoff <28318173+schristoff@users.noreply.github.com>
