Changing instance type recreates the instance and doesnt need to

[gtmtech]

Terraform 0.8.7

If you change the instance type of an instance, when you plan you get:

-/+ aws_instance.foo
instance_type: "m4.2xlarge" => "m4.xlarge" (forces new resource)

However this does not need to be so - the instance can be stopped, instance type changed, and instance type restarted. Doing this means more data is safeguarded (as long as ephemeral disks not used).

It would be better to provide stop/start mechanism
