Have README.md point at CONTRIBUTING.md

Instead of duplicating information about how to build Pulumi from
source in both `README.md` and `CONTRIBUTING.md`, just have the
`README.md` point at `CONTRIBUTING.md`.

Fixes #2197

 This repository does not actually create any real cloud resources as part of testing, but still uses Pulumi.com to store information abot some synthetic resources it creates during testing. Other repositories may require additional setup before running tests (most often this is just setting a few environment variables that tell the tests some information about how to use the cloud provider we are testing). Please see the `CONTRIBUTING.md` file in the repository, which will explain what additional configuration needs to be done before running tests.

-## Development
+## Contributing
 
-If you'd like to contribute to Pulumi and/or build from source, this section is for you.
-
-### Prerequisites
-
-Pulumi is written in Go, uses Dep for dependency management, and GoMetaLinter for linting:
-
-* [Go](https://golang.org/doc/install): https://golang.org/dl
-* [Dep](https://github.com/golang/dep): `$ go get -u github.com/golang/dep/cmd/dep`
-* [GoMetaLinter](https://github.com/alecthomas/gometalinter):
-    - `$ go get -u github.com/alecthomas/gometalinter`
-    - `$ gometalinter --install`
-
-### Building and Testing
-
-To install the pre-built SDK, please run `curl -fsSL https://get.pulumi.com/ | sh`, or see detailed installation instructions on [the project page](https://pulumi.io/).  Read on if you want to install from source.
-
-To build a complete Pulumi SDK, ensure `$GOPATH` is set, and clone into a standard Go workspace:
-
-    $ git clone git@github.com:pulumi/pulumi $GOPATH/src/github.com/pulumi/pulumi
-    $ cd $GOPATH/src/github.com/pulumi/pulumi
-
-The first time you build, you must `make ensure` to install dependencies and perform other machine setup:
-
-    $ make ensure
-
-In the future, you can synch dependencies simply by running `dep ensure` explicitly:
-
-    $ dep ensure
-
-At this point you can run `make` to build and run tests:
-
-    $ make
-
-This installs the `pulumi` binary into `$GOPATH/bin`, which may now be run provided `make` exited successfully.
-
-The Makefile also supports just running tests (`make test_all` or `make test_fast`), just running the linter
-(`make lint`), just running Govet (`make vet`), and so on.  Please just refer to the Makefile for the full list of targets.
