Create a sophisticated deployment test on Windows

[devos50]

For stability, we require a deployment test on our proxmox machines for windows platform (Win7, Win8 & Win10).

I propose that this deployment test does the following operations:

• fetch the latest tribler_setup.exe from Jenkins
• run the installer
• check if Tribler was installed properly
• run Tribler
  • check for dependency errors
  • check if process is running
  • check for errors
• perform REST APIs check
• (optional) take a screenshot
• restore a snapshot of the virtual machine

During the test, there are many sanity checks. If one of these checks fail, we fail the job.
