Notable changes:
* backend/s3: Automatic validation of `eu-north-1` region
* backend/s3: Support for `credential_process` handling in AWS configuration file
Updated via:
```
go get github.com/aws/aws-sdk-go@v1.16.4
go get github.com/terraform-providers/terraform-provider-aws@v1.52.0
go mod tidy
go mod vendor
```
After a bunch of recent changes/rebasing our vendored dependencies got a
little out of sync w.r.t transitive dependencies through codebases that
are not themselves Go Modules yet.
Here we upgrade the AWS Go SDK to 1.12.27 and AWS provider to include terraform-providers/terraform-provider-aws#1608.
This includes the capability to use named credentials profiles from the `~/.aws/credentials` file to authenticate to the backend.
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

* Remove `make updatedeps` from Travis build. We'll follow up with more
specific plans around dependency updating in subsequent PRs.
* Update all `make` targets to set `GO15VENDOREXPERIMENT=1` and to
filter out `/vendor/` from `./...` where appropriate.
* Temporarily remove `vet` from the `make test` target until we can
figure out how to get it to not vet `vendor/`. (Initial
experimentation failed to yield the proper incantation.)
Everything is pinned to current master, with the exception of:
* Azure/azure-sdk-for-go which is pinned before the breaking change today
* aws/aws-sdk-go which is pinned to the most recent tag
The documentation still needs to be updated, which we can do in a follow
up PR. The goal here is to unblock release.
