When using disk_image CD-ROM not needed

Use consistent escaping for ovftool uri creds

Create GCE image from persistent disk instead of from a tarball.

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.

Use golang/oauth2, no longer require client_secrets.json, and use

Service Account when run from a GCE Instance.

Added the Ubuntu image project for GCE.

The documentation:
https://cloud.google.com/compute/docs/operating-systems#ubuntu
shows that `ubuntu-os-cloud` is the proper project name.

I got thrown for a loop since the username is uri-escaped but the password was not.

I got thrown for another couple of loops due to the multiple levels of interpretation involved:
1) JSON syntax requires backslashes to be slash-escaped. Some vCenter deployments use windows domain-style usernames DOMAIN\user
2) the OVFTOOL docs specify that "all special characters" be uri-encoded when part of the user name or password
3) different shell interpretations on windows/linux

I'd say escape both or neither.
