Actually, this has percolated a bit and I'm not so happy. This is quite
a big and magical behaviour change... I have on a few occasions
needed/wanted to upload tools that *don't* match the juju binary I'm
using, and this kinda breaks that. Can still be worked around; and
should probably only affect developers; but I'm starting to think that
it's wrong to piggyback on the upload-tools mechanism for this use case.

I should be around tonight to talk about it a little... my big concern
is that we're changing behavior that *will* affect all the users who are
using upload-tools. Maybe I can be convinced that it's only a little,
and maybe even a beneficial, change; but let's discuss tonight.
