I've created a patch for JMXConfiguratorAction that allows it to take a
configuration attribute (optional) that will scope the MBean:

<jmxConfigurator namespace="your_custom_tag"/>

This will register the MBean with an ObjectName of
"ch.qos.logback.classic:Name=default,Type=ch.qos.logback.classic.jmx.ConfiguratorMBean,namespace=your_custom_tag".

It is perhaps not the cleanest solution, but at least it provides some way
to control the scoping of the MBean in a multi-application environment.

Let me know if this is a good idea, and I will post the patch to JIRA!
