It's missing a bunch of stuff, for sure, like parameters, tests, docs,
etc, and I haven't actually run it against aws, but I have what I think
is all of the boilerplate required, so it's a start

I grabbed all of these from the API docs:
https://docs.aws.amazon.com/sdk-for-go/api/service/opsworkscm/#CreateServerInput

It's still not entirely there, and I'll need to document the
instance/service profile ARN stuff, and the security groups since
I think the security groups need to be made outside and not automanaged
by the server resource on AWS's side

everything is there but the EngineAttributes bit and validation.

also debating still on whether some of those required params should be
optional. I'd like them to be required, but I'll have to ask upstream
their thoughts

They already are required because of the way I made the Create function,
so while it's still an open question whether or not they should actually
be required required, I at least want to make it consistent at the
moment

I think this is the baseline requirements for setting up the
opsworks_chef instance. It's ... verbose. But this is also a fairly
complex thing to be creating, so that's kinda to be expected, methinks.

per discussion in the PR, I think ForceNew here is probably a bad idea
because it will almost certainly destroy any node associations, but at
least it won't silently do nothing :)

since this doesn't seem to be running yet (I think this only runs in
acceptance tests?) it doesn't explode, but I'm testing something like it
elsewhere
