Maybe we can just copy the entire factory folder to tmp rootfs?

Temporarily assign to Nooger. yllin, you can try to see if there's something can be improved here.

deploy_utils: FactoryBin for using local factory toolkit.

To generalize testing flow, it would be better to have a common API for
'gooftool' and 'hwid' provided by either a factory python archive or
local factory toolkit.

FactoryBin is a counterpart of FactoryPythonArchive, which invokes
python scripts under factory/bin rather than a factory python archive.

And class FactoryTools is an abstract class to unify APIs of FactoryBin
and FactoryPythonArchive.

We are still using factory.par for wipe_init, right?

> We are still using factory.par for wipe_init, right?
yes

So what should we do here? copy /usr/local/factory to wiping env instead of using factory.par?

Yes, and maybe some external deps too.
