[test] packaging: add windows boxes

Adds windows server 2012r2 and 2016 vagrant boxes to packaging tests.
They can only be used if IDs for their images are specified, which are
passed to gradle and then to vagrant via env variables. Adds options
to the project property `vagrant.boxes` to choose between linux and
windows boxes

Bats tests are run only on linux boxes, and portable packaging tests run
on all boxes. Platform tests are only run on linux boxes since they are
not being maintained.

-The simplest way to test scripts and the packaged distributions is to use
-Vagrant. You can get started by following there five easy steps:

+These tests should really only be run in vagrant vms because they're destructive.

+be downloaded again unless they have been updated to a new version.
 
 . Run the tests with `./gradlew packagingTest`. This will cause Gradle to build
 the tar, zip, and deb packages and all the plugins. It will then run the tests
 on ubuntu-1404 and centos-7. We chose those two distributions as the default
 because they cover deb and rpm packaging and SyvVinit and systemd.
 
-You can run on all the VMs by running `./gradlew -Pvagrant.boxes=all
-packagingTest`. You can run a particular VM with a command like `./gradlew
--Pvagrant.boxes=oel-7 packagingTest`. See `./gradlew tasks` for a complete list
-of available vagrant boxes for testing. It's important to know that if you
-interrupt any of these Gradle commands then the boxes will remain running and
-you'll have to terminate them with `./gradlew stop`.
+You can choose which boxes to test by setting the `-Pvagrant.boxes` project property. For
+example, to test all boxes, run `./gradlew -Pvagrant.boxes=all`. For a complete list of
+available boxes, run `./gradlew :qa:vagrant:tasks --all`. All of the following values are
+supported by the `vagrant.boxes` property
+
+* `sample` - The default, only chooses ubuntu-1404 and centos-7
+* `all` - All configured boxes, i.e. all linux boxes and any configured Windows
+boxes.
+* `linux-all` - All linux boxes.
+* `windows-all` - All configured Windows boxes. If there are none configured when this
+value is set, the build will fail.
+* List of box names, comma separated (e.g. `oel-7,fedora-26`) - Chooses exactly the boxes listed.
+
+Note that if you interrupt gradle in the middle of running these tasks, any boxes started
+will remain running and you'll have to stop them manually with `./gradlew stop` or
+`vagrant halt`.
 
 All the regular vagrant commands should just work so you can get a shell in a
 VM running trusty by running
 `vagrant up ubuntu-1404 --provider virtualbox && vagrant ssh ubuntu-1404`.

+The packaging tests also support Windows Server 2012R2 and Windows Server 2016.

+Specify the image IDs of the Windows boxes to gradle with the following environment

 them and let vagrant reprovision them. Say you've hosed your precise VM:
