Subject: [PATCH] Handle plugin prefixes in implementation logging
 configuration

Currently, plugin prefixes are prepended to the log message in
the PluginLogger before passing the message to the underlying
logging framework. This is bad design because they need to be
stripped manually when using custom appenders to log messages
in a different format.

Additionally, it makes integration of alternative logging APIs hard
because all logging must go through the PluginLogger. Avoid using
PluginLogger and create a regular logger using the plugin name.
The implementation should handle plugin prefixes by displaying
logger names when appropriate.
