Description

aws_subnet_ids data source modified so the vpc_id argument is not required. The DescribeSubnets API call does not require vpc_id to be specified. Use case is want to return all subnets (regardless of vpc_id) which match a filter condition, in this case OutpostArn=value. Then use those subnets arns in a policy to deny launching in any subnet which is not an located on an Outpost, thus implementing a preventative control to enforce data residency

Not sure whether removing vpc_id would be a breaking change.
Maybe we can take the opportunity to introduce a new data source aws_subnets (which conforms to the preferred naming), without the vpc_id attribute, and deprecate aws_subnet_ids?

I would be fine with a new data source
