Support identifying different tgz files based on run_label attribute
tgz files in trials can be categorized in subdirectories, allowing to select different bianry files at runtime based on the target run node which is going to run them. This way for instance one can have a binary linked against libs for eg. CentOS under run_label "centos/" or an ARM target under "arm", and then use "run_label: arm" on the resource using it.
