Support for Windows 10 hosts with OpenSSH

[ciarancourtney]

As of 2018 Windows 10 comes with an optional OpenSSH server. By default clients are given a remote shell to cmd but you can specify an alternative (like Git Bash) in the registry like so:

New-ItemProperty -Path "HKLM:\SOFTWARE\OpenSSH" -Name DefaultShell -Value "C:\Program Files\Git\bin\bash.exe" -PropertyType String -Force

With Fabric:

Here is some sample output

test -d buildbot-worker  # ok
hostname  # ok
windows-10-x64
mkdir -p buildbot-worker  # not ok
mkdir: missing operand
Try 'mkdir --help' for more information.

I realize this opens a can of worms, most of which is probably due to problems with the very beta state of win10 OpenSSH and compounded by using git bash, but maybe this issue can track workarounds/docs on how to support the use case better?

WSL is another option, but not suitable for when you want nix-y native-ish windows command that mingw gives you
