Fix the broken check state logic
Fix support for allow-hotplug statement in debian_ip network module

When an existing interface was configured with allow-hotplug or when setting
"hotplug: True" in network.managed state, this was not taken into account and
the allow-hotplug setting would be removed from /etc/network/interfaces.

This patch fixes this issue.

win_pkg: `_get_msi_software` uses COM instead of WMI

WMI queries against `Win32_product` have a nasty side effect of
triggering a "repair" operation on all installed software (see
[KB974524][]), which can kill the `TrustedInstaller` service.

Workaround is to use the `WindowsInstaller.Installer` COM object, and
it's [ProductsEx][] property. Unfortunately,
`WindowsInstaller.Installer.ProductsEx` is a "get property" that takes
3 arguments, and [I can't figure out how to call that from
python][SO23497599].

This Runs some powershell (via `cmd.run_all`) to get the name/version
from COM, then parse the results in python to build the dictionary.

Tested by deploying this function as a custom module to a variety of
windows servers and running it, covering:

* no powershell
* powershell v1
* powershell v2
