feel like the defining the signals for Windows was originally a band-aid, and understand this
patch didn't add them.

could be any number so long as only the symbol is used in the rest of the code base. I think
this is why this worked anyway.

I think they worked before because they were used only within stout. One of the docker executor
method signature is `docker->kill(ID, SIGNAL)`, which eventually calls `docker kill -s
SIGNAL ID`. Docker (and go standard library) defines the Linux signal values on Windows, so
it's expecting `docker kill -s 9`. If you want, I can fix the docker executor to ignore the
signal field on Windows and just send `docker kill` without the `-s`.
