@Leila-Kuntar Thanks for this!

See comment.

@Wyosotis PTAL. Apologies, I didn't click the "submit review" here. I seem to be on a roll this week, sorry about that...

[Temikus]

This probably should be in "development" spec group, no?
I don't want us to have a hard dependency on rake version in the driver.

@Temikus PTAL
I have updated it but now there is other problem. The file lib/vagrant-google/config.rb has been changed a few days ago. So rake tests fail due to changes in pull #167 (65 examples, 6 failures).

Thanks @Wyosotis! @Temikus rolled this fix into #174 and we cut a new release.
