* Moving certain documents to the dotnet/core repo
Moving the following documents to the dotnet/core repo, to make maintenance easier and also to keep all of the various support documents for .NET Core all-up in the same place.
The documents changed:
* supported-os-matrix.md
* known-issues.md
* cli-prerequisites.md
Also editing the README.md document to point to the new repo and its documents where needed.
* Add pre-reqs doc to the repo
This document outlines all of the native dependencies that are needed to run the CLI tools for Ubuntu, Windows, CentOS and OS X.
As per chat with @leecow documentation does not need special approval to get merged.

* Update cli-prerequisites.md
* Responding to PR feedback
I've changed the Ubuntu reqs to be the same as CentOS pre-reqs just with the correct package names. This seems like a more sane thing to do.
