Currently we have python code duplicated in few locations:
 
 - /usr/local/factory/py
 - /usr/local/factory/factory.par
 - /usr/local/factory-mini/factory-mini.par

Roughly:
 - factory-mini.par contains everything needed to run shopfloor & gooftool
 - factory.par added pytests & goofy (for remote offline mode tests to run)
 - /usr/local/factory contains everything

However this is causing issues today because 
 - stateful partition is getting smaller space
 - downloading and uploading toolkit in factory with limited network is painful
   (a 25M toolkit may take 10 min to download / upload)

Maybe we can revise and clean up for what should be contained in toolkit, for example
 - is goofy needed in factory.par
 - do we really need factory.par in every toolkit
 - can we include factory.par only if needed on particular boards (since we will now use local toolkit first)
