Add ProcessMonitoring Component

[BenLewies]

Monitor specific processes to check if they are running. If not, start them up again with given startup parameters.

One sample use case is running Docker Desktop on Windows Server with support for Linux containers, which is not supported when running the Docker Windows Daemon. Using this component, we will be able to automatically start up Docker after it terminated or the host was restarted.

Update Readme as well.

As in the case of Docker Desktop, Zombie or Dangling processes can prevent this functionality from working as expected, as Lifeguard will still see these processes are running and not restart the service.

Also not for the described Docker use case this solution will not work - Windows requires a logged in user for Desktop applications to run.
