Windows support for Fleetctl

[Xe]

Unfortunately, I find myself working on windows a lot as of late, and I would like to have fleetctl running on windows. Thankfully it builds normally, but at runtime it fails due to the lack of an ssh-agent domain socket. Windows doesn't support the idea of domain sockets, and I don't use cygwin on my windows machine.

Could there a way to instead hardcode an SSH key for fleetctl use? Perhaps something like FLEETCLT_SSH_PRIVATE_KEY or an equivalent?

This also fixes the root problem of deis/deis#2607.

This seems reasonable. I would prefer to see it implemented as a -i/--identity-file to follow openssh's lead which could then be set using FLEETCTL_IDENTITY_FILE.

Any update ?

I personally don't have the time to work on this. If anyone wants to tackle it, I would be more than happy to review.
