[python-win32] Dispatching something that requires elevation

[Vernon D. Cole]

look in github.com/salt-bevy/sudo.py
<https://github.com/salt-bevy/salt-bevy/blob/master/configure_machine/sudo.py>
for a module which will request elevated privileges for a Python script
running as a normal user.
Perhaps that can help create a solution for your use case.

There is a sample call for it in bootstrap_bevy_member_here.py or you can
just run it from the command line with the script you want to run as
administrator as its arguments.
