Title: (PUP-2828) puppet-win32-ruby acceptance ver config

- Previously, Jenkins acceptance jobs on Windows would clone Windows
source for puppet-win32-ruby, the vendored Ruby that we ship as part
of Windows MSI builds. This comes from an internal git mirror.
- At present, a simple checkout is performed against whatever is the
'default' branch (typically the 1.9.3 branch). Unfortunately, this
will not work for any acceptance jobs that intend to use 2.0, and it
currently doesn't work for jobs that need new versions of gems.
- Rather than take a clone the repo and hope it works approach, make
use of Beaker's 'rev' option when calling install_from_git.

- Using :rev allows us to pin the repo version by using an environment
variable that can be setup in the Jenkins job. This variable is
called WIN32_RUBY_SHA, but realistically can use a git commit-ish as
specified in the git documentation for checkout -f
https://www.kernel.org/pub/software/scm/git/docs/git-checkout.html
It will accept a branch, tag, SHA, etc
- The default :rev is set to '' so that prior behavior is preserved
