(aws-ec2): (ec2.Instance should delete the Instance policies from the Instance role it builds out)

[arbeiterz]

Describe the feature

On attempting to perform a "cdk destroy" against a stack which deployed an instance with ec2.Instance, CDK refuses to destroy it and complains about the fact that the policies must first be removed from the role. With this feature in place, CDK would recognize that CDK itself had built the role and take steps to remove the policies and delete the role along with the instance.

Use Case

I would like to be able to simply call, "cdk destroy" against a stack that deployed an EC2 instance with ec2.Instance() and have the instance destroyed without having to do manual clean up. This is why I want to use CDK to begin with - so I don't have go manually cleaning up a bunch of stuff.

Proposed Solution

Have CDK recognize the fact that ec2.Instance is contained in the stack and therefore it should expect to have to clean up the role properly on instance deletion.
