Uninstall fails upon error. This has bad consequences for cleaning up partial installs. Here's what I see:
1. Run install to create a chain of dependent nodes, say network -> subnet -> port -> instance. 2. For whatever reason, install fails on "create port" for example. 3. Running uninstall fails immediately trying to delete the instance. Is there a way to make uninstall behave like Cloudify (IOW continue on error)?
