Pulled the code from RunScriptCommand as an example, and I think I'm good in
that respect.
I'm having issues with runScriptOnNodesMatching() when I want to only run
the script on 1 node in the group. I have the node Id of the target node,
but not sure how to create a predicate that just targets one node based on
the Id. NodePredicates.withIds() returns a
Predicate<ComputeMetadata>, but runScriptOnNodesMatching
takes a Predicate<NodeMetadata>.
The jclouds wiki states "Individual commands are executed against a specific
node's id", but that doesnt really explain how to do this.
