[JENKINS-21602] Option to exclude off-line Slaves in "Individual Slaves"

I would like to use a Matrix Job to release software to Jenkins Master and Slaves. Unfortunately, if any slave is off-line the job never finishes which means it will not run again (at the next release) without manual intervention. I would either like an "on-line slaves only" option, or for something like this to work as a combination filter:

Hudson.instance.getComputer(label == "master"?"":label).getNode().getChannel() != null

The above scriptlet works fine in scriptler, but I cannot seem to get it running (with or without an import) in the combination filter. The combination box will not properly process "import" and without the import "Hudson" is undefined.

Start by locating the matrix-project-plugin code for the “Individual Slaves” configuration and combination filter, then review how offline slaves and filter scripts are evaluated. Done means an explicit online-slaves-only behavior or a working equivalent filter that prevents offline slave combinations from blocking the matrix job.
