Rename files before upload to AWS nodes

[pbiology]

What needs to be done:
In order to avoid issues with sensitive information being sent to cloud, we could do a pre-step with a local executor. If we re-name files locally, keep a dictionary in memory and then re-name the files again once they return from the cloud nodes, then we can avoid sending labIDs to the cloud.

Suggestions on how to get it done:
Before the rest of the workflow is executed, run a step with a local executor for file renaming. One perhaps need to be a little careful not to use up all resources on the login node.

What are the arguments for getting it done:
We can side-step some of the legal issues hopefully
