Add SSM agent policy to instance profile, add name tag to autoscaling group

I also ran terraform fmt, which unfortunately makes diffing the changes hard, so here are links to the main changes: https://git.doit.wisc.edu/interop/iics/iics_secure_agent/blob/a76b8a5a9211346bfa418dc61e5cb5f32ce05e75/terraform/autoscaling-group.tf#L14-18 https://git.doit.wisc.edu/interop/iics/iics_secure_agent/blob/a76b8a5a9211346bfa418dc61e5cb5f32ce05e75/terraform/iam.tf#L26-30

@NUWAN.KUMARASIRI could you review and then deploy if everything looks good?
