Switch to using the wmi-lite gem

[btm]

Chef switched from ruby-wmi to wmi-lite recently, have this cookbook do the same.

This replaces #100, and I'm handing this off to @Adamex to finish. I think the only work left is to think about making sure that wmi-lite is installed before the libraries need it if you're running on older versions of Chef that don't come with wmi-lite. Later we should deprecate the windows/libraries/version.rb in favor of `lib/chef/win32/version.rb' in chef.

I've been testing with this recipe to make sure we exercise the libraries, as the default cookbook was happily running for me with just @pieter-lazzro's patch before I did so.

winver = Windows::Version.new

log "server core" do
  message "not on server core"
  not_if { winver.server_core? }
end

hive_name = Registry.get_hive_name("HKLM")

log "hive name" do
  message "HKLM is really #{hive_name}"
end

log "not media center" do
  message "we are not on media center"
  not_if { Registry.value_exists?(AUTO_RUN_KEY, 'Windows Media Center') }
end

Resulting in:

Recipe: win_test::default
  * log[server core] action write[2014-08-04T14:35:52-04:00] INFO: Processing log[server core] action write (win_test::default line 4)
[2014-08-04T14:35:52-04:00] INFO: not on server core


  * log[hive name] action write[2014-08-04T14:35:52-04:00] INFO: Processing log[hive name] action write (win_test::default line 11)
[2014-08-04T14:35:52-04:00] INFO: HKLM is really HKEY_LOCAL_MACHINE


  * log[not media center] action write[2014-08-04T14:35:52-04:00] INFO: Processing log[not media center] action write (win_test::default line 15)
[2014-08-04T14:35:52-04:00] INFO: we are not on media center

Thanks btm. Have just started using chef and ruby and my use case was very simple and don't think I actually hit the code I changed.

@danielsdeleo , @btm, @sersut , @juliandunn, can you take a peek? Not sure if this is the best way to try to use chef_gem to satisfy a gem dependency in a library file.

[adamedx]

So you're the only other person besides me @btm running Windows Media Center?

[btm]

It came free with my pro upgrade ¯_(ツ)_/¯

FWIW, its a really nasty undefined method '[]' for nil:NilClass error if your SKU isn't in the constant :(

[danielsdeleo]

The gem install stuff is ugly, but I don't know how to do it better without some support from Chef, which is something we've thought about but don't have a design for (and that wouldn't help immediate pain anyway). 👍

[adamedx]

Thanks @btm, @danielsdeleo. Yeah, ideally you could express the gem dependencies in metadata.rb or even in a gemspec-like file. Then gems could be downloaded to a bundle for the cookbook when cookbooks are fetched. Crazy talk.

Tested on 11.12.8, 11.14.2, and 10.32.2 successfully.
