Terraform crashes with interface conversion in GCE Instance Template

[j-oconnor]

Seems to be related to the disk_size_gb arg.

panic: interface conversion: interface is int, not int64

Not sure if I'm expected to create the disk separately then reference it in to the template. The disk_size_gb arg isn't documented, but i saw the code was there and its supported by API.

I'm on 0.6.2dev built from master. I can duplicate readily just using the sample code from docs and adding "disk_size_gb = 20" on the boot disk. I'll post the crash.log if needed.

I got it to work on my local with simple typecast.

I have same issue with disk_size_gb in google_container_cluster.node_config
