- startup scripts don't run for Windows since it is isn't implemented yet.
- startup scripts use instance metadata instead of serial port output to flag when they are done.
- added licenses to Image data type (to check if an Image is a Windows Image).
- added GetImage and GetImageFromProject to googlecompute Drivers.
- changed some of the builder/googlecompute tests to use github.com/stretchr/testify/assert.
Tests:
- (in the Packer directory) `go test .`, `go test ./builder/googlecompute`, and `go test ./post-processor/googlecompute-export`
- manual run of `packer build packer_template.json` with the following files
