jclouds Development Tools

This dir would be made up of sub-dirs that hold scripts and config that help us develop jclouds.

No release artifacts would be created from this dir or stored in this dir.
Remove this from the PR? I think it's fine to have shell scripts only - let's skip on the duplicate maintenance? I and other Windows users should always be able to find a VM, and I'm happy to keep hosting a Windows version on my ASF page.
