Replace godep with vndr

Vndr has a simpler configuration and allows pointing to forked
packages. Additionally other docker projects are now using
vndr making vendoring in distribution more consistent.

Updates letsencrypt to use fork.
No longer uses sub-vendored packages.

-Go is an open source project.
-
-It is the work of hundreds of contributors. We appreciate your help!

-## Filing issues
-
-When [filing an issue](https://github.com/golang/oauth2/issues), make sure to answer these five questions:
-
-1. What version of Go are you using (`go version`)?
-2. What operating system and processor architecture are you using?
-3. What did you do?
-4. What did you expect to see?
-5. What did you see instead?
-
-General questions should go to the [golang-nuts mailing list](https://groups.google.com/group/golang-nuts) instead of the issue tracker.
-The gophers there will answer or ask you to file an issue if you've tripped over a bug.
-
-## Contributing code

-**We do not accept GitHub pull requests**
-(we use [Gerrit](https://code.google.com/p/gerrit/) instead for code review).

-[![Build Status](https://travis-ci.org/golang/oauth2.svg?branch=master)](https://travis-ci.org/golang/oauth2)
-
-oauth2 package contains a client implementation for OAuth 2.0 spec.

-## Installation

-go get golang.org/x/oauth2

-## App Engine
-
-In change 96e89be (March 2015) we removed the `oauth2.Context2` type in favor
-of the [`context.Context`](https://golang.org/x/net/context#Context) type from
-the `golang.org/x/net/context` package
-
-This means its no longer possible to use the "Classic App Engine"
-`appengine.Context` type with the `oauth2` package. (You're using
-Classic App Engine if you import the package `"appengine"`.)
-
-To work around this, you may use the new `"google.golang.org/appengine"`
-package. This package has almost the same API as the `"appengine"` package,
-but it can be fetched with `go get` and used on "Managed VMs" and well as
-Classic App Engine.
-
-See the [new `appengine` package's readme](https://github.com/golang/appengine#updating-a-go-app-engine-app)
-for information on updating your app.
-
-If you don't want to update your entire app to use the new App Engine packages,
-you may use both sets of packages in parallel, using only the new packages
-with the `oauth2` package.
