aws_instance metadata_options don't honor the defaults

[acdha]

Description

The EC2 aws_instance resource lists several options with default values:

https://www.terraform.io/docs/providers/aws/r/instance.html#metadata-options

Unfortunately, you have to specify these values to have Terraform successfully create the resource.

Odd - #12564 has the exact error message but Github search didn’t turn it up before I opened this issue. I’m inclined to close this as a duplicate.
