Ops: Windows Vagrant box

Added project https://github.com/rgl/windows-vagrant as a submodule. General scheme of getting this to work was something like this:

• Clone repo
• use make to create a desired image from list - for list do make help
• wait for like 50 minutes because its so slow
• If it hangs on any step (i.e. waiting for ssh to become available) let it run, it's going, just not very fast.
• After box has been created, add it to vagrant where name of the freshly created box is required - console log will tell you proper command to execute
• Now you may use that new box in vagrant almost as any other box.

Now the caveats

• As stated before, it takes long time to build.
• Takes a hefty amount of space as well.
• Vagrant does not support linux in filesystem mounting via samba https://www.vagrantup.com/docs/synced-folders/smb and that is preferred way in windows-vagrant as visible in examples.

To do:

• Find a way to share project folder with windows box
• Create a proper provisioning script, probably using Chocolatey - windows "package manager"
• Try building timebox on windows machine
