Bundle format test and documentation
We should try our bundle import and export CLI functionality on our first two example uploads. David implemented this, but I am not sure what we actually have here. I want to see what this can already do and what not. We need this as a starting point for further discussions on data transfer.
As a side effect, please extend the documentation with a brief "how to import and export uploads". This should cover the commands and a rundown on the bundle format, e.g. what files it contains, whats in the nomad.json, etc. We can put this under "NOMAD Oasis" for now.
