I would like to use the LocLogger to provide message catalogs in my application.

However, I also use Markers with my logger to allow for more complex filtering rules using a turboFilter.  I can't use both given the API in org.slf4j.cal10n.LocLogger.

Using MDC isn't an option as the code is running inside a Vert.x event loop and use of thread locals doesn't work in that world.

I can provide a PR if you're willing to accept one.
