* removed packer.Cache and references since packer.Cache is never used except in the download step. The download step now uses the new func packer.CachePath(targetPath) for this, the behavior is the same.
* removed download code from packer that was reimplemented into the go-getter library: progress bar, http download restart, checksuming from file, skip already downloaded files, symlinking, make a download cancellable by context.
* on windows if packer is running without symlinking rights and we are getting a local file, the file will be copied instead to avoid errors.
* added unit tests for step_download that are now CI tested on windows, mac & linux.
* files are now downloaded under cache dir `sha1(filename + "?checksum=" + checksum) + file_extension`
* since the output dir is based on the source url and the checksum, when the checksum fails, the file is auto deleted.
* a download file is protected and locked by a file lock,
* updated docs
* updated go modules and vendors
This seemed to be missing from the googlecompute provider. Now if the
ssh_private_key_file is provided, that will be used in place of a temporary
key. I didn't update the googlecompute specific docs under `./website/`, since
this parameter is already documented under the communicators templates page.
- 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
--packer_template.json--

- Startup scripts can be provided through the instance creation metadata field 'startup-script'.
- Script log can be copied to a GCS location by setting the metadata field 'startup-script-log-dest'.
Added Retry method to googlecompute package.
Added GetSerialPortOutput to googlecompute Drivers.
Added StepWaitInstanceStartup (and associated test) which waits for an
instance startup-script to finish.
Changed the instance service account to use the same service account as the one provided in the Packer config template. It was the project default service account.
Tested googlecompute package with 'go test' and also performed builds
with a startup script and without a startup script.
The new flow:
1) Provision the instance
2) Tear down the instance, but keep the boot disk
3) Create an image from the disk
4) Tear down the disk
The step to update gcloud is no longer needed, since gceimagebundle isn't used anymore.
Fixes#1507 and addresses https://github.com/mitchellh/packer/issues/1447#issuecomment-61610235.
