* govendor fetch cloud.google.com/go/bigtable
* Vendor the rest of the stuff.
* Add support for instance_type to google_bigtable_instance.
* Revendored some packages.
* Removed bad packages from vendor.json
* vendor: Ignore github.com/hashicorp/terraform/backend

when we don't really need remote backend functionality
in provider code - it's core's responsibility.
* vendor: github.com/hashicorp/terraform/...@v0.10.0
