Vendor or shade the dependencies of beam-sdks-java-io-google-cloud-platform

Here at Spotify, we regularly face conflicting dependencies issues, usually caused by guava, grpc-* and netty-*. Looking at this bug tracker, it seems that we are not alone and that conflicting versions are a recurring issue.

In beam-sdks-java-core, beam-runners-direct-java and beam-runners-google-cloud-dataflow-java those dependencies are vendored to avoid such issue.

I suggest to do the same for beam-sdks-java-io-google-cloud-platform.

FIY, here's the list of all the dependencies pulled by beam-sdks-java-io-google-cloud-platform:
