Michal Privoznik 0287b5dfd2 tools: Introduce SSH proxy
This allows users to SSH into a domain with a VSOCK device:

  ssh user@qemu/machineName

So far, only QEMU domains are supported AND qemu:///system is
looked for the first for 'machineName' followed by
qemu:///session. I took an inspiration from Systemd's ssh proxy
[1] [2].

To just work out of the box, it requires (yet unreleased) systemd
to be running inside the guest to set up a socket activated SSHD
on the VSOCK. Alternatively, users can set up the socket
activation themselves, or just run a socat that'll forward vsock
<-> TCP communication.
