Import grpcio-sys 0.6.0

And add metadata files using the following command:
get_rust_pkg.py --add3prf -v grpcio-sys-0.6.0 -o grpcio-sys

Use LICENSE file from parent grpcio crate. Add README.android
as requested during security review.

+gRPC - An RPC library and framework
+===================================
+
+gRPC is a modern, open source, high-performance remote procedure call (RPC) framework that can run anywhere. gRPC enables client and server applications to communicate transparently, and simplifies the building of connected systems.

+
+# To start using gRPC
+
+To maximize usability, gRPC supports the standard method for adding dependencies to a user's chosen language (if there is one).
+In most languages, the gRPC runtime comes as a package available in a user's language package manager.
+
+For instructions on how to use the language-specific gRPC runtime for a project, please refer to these documents
+
+ * [C++](src/cpp): follow the instructions under the `src/cpp` directory
+ * [C#](src/csharp): NuGet package `Grpc`
+ * [Dart](https://github.com/grpc/grpc-dart): pub package `grpc`
+ * [Go](https://github.com/grpc/grpc-go): `go get google.golang.org/grpc`
+ * [Java](https://github.com/grpc/grpc-java): Use JARs from Maven Central Repository
+ * [Kotlin](https://github.com/grpc/grpc-kotlin): Use JARs from Maven Central Repository
+ * [Node](https://github.com/grpc/grpc-node): `npm install grpc`
+ * [Objective-C](src/objective-c): Add `gRPC-ProtoRPC` dependency to podspec
+ * [PHP](src/php): `pecl install grpc`
+ * [Python](src/python/grpcio): `pip install grpcio`
+ * [Ruby](src/ruby): `gem install grpc`
+ * [WebJS](https://github.com/grpc/grpc-web): follow the grpc-web instructions
+
+Per-language quickstart guides and tutorials can be found in the [documentation section on the grpc.io website](https://grpc.io/docs/). Code examples are available in the [examples](examples) directory.
+
+Precompiled bleeding-edge package builds of gRPC `master` branch's `HEAD` are uploaded daily to [packages.grpc.io](https://packages.grpc.io).
+
+# To start developing gRPC
+
+Contributions are welcome!
+
+Please read [How to contribute](CONTRIBUTING.md) which will guide you through the entire workflow of how to build the source code, how to run the tests, and how to contribute changes to
+the gRPC codebase.
+The "How to contribute" document also contains info on how the contribution process works and contains best practices for creating contributions.
+
+# Troubleshooting
+
+Sometimes things go wrong. Please check out the [Troubleshooting guide](TROUBLESHOOTING.md) if you are experiencing issues with gRPC.
+
+# Performance 
+
+See the [Performance dashboard](https://performance-dot-grpc-testing.appspot.com/explore?dashboard=5652536396611584) for performance numbers of master branch daily builds.
+
+# Concepts

+See [gRPC Concepts](CONCEPTS.md)
+
+# About This Repository
+
+This repository contains source code for gRPC libraries implemented in multiple languages written on top of a shared C core library [src/core](src/core).
+
+Libraries in different languages may be in various states of development. We are seeking contributions for all of these libraries:
+
+| Language                | Source                              |
