Using the ContextClassLoaderLogContextSelector causes static loggers loaded from libraries that set the TCCL to a deployments class loader get configured with the incorrect log context.

<dmlloyd> each Class object is examined for its class loader
<dmlloyd> we keep a set of our logging API class loaders
<dmlloyd> we iterate until we find a Class which isn't in one of our known modules
<dmlloyd> then we use that Class's class loader to select the log context
