Show logs from logging-profile in log viewer

We're using a farm of Wildflies to run a bunch of different applications. For that reason, we use "per Application" logging with different logfiles for each application. To structure that, each application use it's own separate subdirectory at jboss.server.log.dir, like ${jboss.server.log.dir}/application-name/transactions.log

We request to support subdirectories for logfiles at all levels, i.e. starting with the model and the CLI / REST interface to the HAL.

IMHO, first at all the enumerator used by /subsystem=logging:read-children-names(child-type=log-file) have to recurse into directories for that.
