Add ingress-shim controller to create Certificates based on annotations on ingress resources
**What this PR does / why we need it**:
Adds a new controller, ingress-shim, that will automatically create Certificate resources for ingress resources with annotations on them.
By setting defaults on the ingress-shim CLI, it's possible to re-implement the `kubernetes.io/tls-acme` behavior of kube-lego.
There also needs to be some documentation written about this, as well as a user guide. This can be our migration story for users coming from kube-lego as well. It'd be interesting to know how easily it'd be to support a seamless migration from [kube-cert-manager](https://github.com/PalmStoneGames/kube-cert-manager) through this tool too.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
Fixes#19
**Special notes for your reviewer**:
This includes unit tests for sync.go in the new controller, as well as a basic e2e test that ensures an ACME certificate is obtained correctly when an annotation is set on an ingress.
**Release note**:
```release-note
Add ingress-shim controller to automatically create Certificate resources based on annotations on ingresses. This allows for easy creation of Certificate resources when using ingress.

Update to go 1.9
1.10 isn't too far off, at which point 1.8 will no longer receive security updates. It seems simple enough to bump sooner rather than wait until the last second.
