win_servermanager.py should check win version and bitness

[twangboy]

win_servermanager.py relies on the ServerManager powershell module.

The ServerManager module is only available on 64bit windows versions 2008R2 and higher.

If a user (for some horrible reason) has 32bit salt installed on 64bit Windows 2008R2 or higher, it will launch a 32bit powershell window which will not be able to find the ServerManager module and will return the following to the master:

        :
    Add-WindowsFeature:

        valid module file was found in any module directory.

        Add-WindowsFeature : The term 'Add-WindowsFeature' is not recognized as the

        spelling of the name, or if a path was included, verify that the path is
        correct and try again.

        + Import-Module ServerManager ; Add-WindowsFeature -Name Web-Server
        -erroraction  ...
        +                               ~~~~~~~~~~~~~~~~~~

A check should be made in the virtual function to check for versions higher than 2008R2 and 64bitness.
