Some argument to dtrace(1) would ideally make it obvious what VMs (and VM types) could be traced #138

A key feature of DTrace is its moderate(ish) discoverability properties -- e.g., you can use dtrace -l to list probes, but also the available modules, etc. It would be nice to have something similar (but maybe only loosely) for discovering available VMs or VM properties that could be used in the 5-tuple.

We have some rudimentary code for this in the form of dtrace -M on the latest commit. We could do more, but the amount of work required to make it print useful information increases quite quickly.
