[Enhancement]: CloudFormation StackSets: Allow `stack_instance_summaries` to be omitted from state.

[marcgreenstock]

Description

The aws_cloudformation_stack_instances and aws_cloudformation_stack_set_instance resources retain a list of instances in state (stack_instance_summaries).

This causes problems when there are many (1000+) instances, such as taking a long time refreshing the state and potential timeouts.

It would be helpful have the ability to disable fetching and persisting the instances.

Affected Resource(s) and/or Data Source(s)

• aws_cloudformation_stack_instances
• aws_cloudformation_stack_set_instance

Potential Terraform Configuration

resource aws_cloudformation_stack_instances.example {
  stack_set_name = aws_cloudformation_stack_set.example.name
  disable_stack_instance_summaries = true
}
