No support for running Windows agent as domain user

[rosenbergj]

There does not appear to be support for running the Windows agent as a domain user.

I created a domain user domain.com\ddwinagentuser. I then deployed a new machine with no Datadog agent installed, and puppet configuration like:

    class {'datadog_agent':
      dd_user               => 'ddwinagentuser',

After puppet finishes running, the agent service is running as the local ddagentuser user rather than the specified domain user.

There are Datadog-supplied instructions about installing the agent as a domain user, but the code at https://github.com/DataDog/puppet-datadog-agent/blob/main/manifests/windows.pp#L77 does not seem to support the necessary options.
