There is 1 breaking change. The OpsWorks Update API no longer supports
`tenancy` as an update. So that has to be marked as ForceNew: true

`publicly_accessible` to be changed
Also updated the AWS Go SDK from 1.1.9 -> 1.1.12 as this was required to
allow the new behavior for the Redshift API
We had actually caught mismatched deps versions between the `kms`
package and others, so `godep restore` was not working on master.
Fixing it requires a `godep update` so I figured we might as well update
to the latest release.
