…3045)

This PR bakes the gRPC plugin in the hermetic library generation image.
The approach is very similar to
googleapis/sdk-platform-java#2707
 * The docker image will have a configurable `ARG` for the gRPC plugin
* The docker image will download the gRPC plugin at the version
specified in the previous point
* The docker image will set the variables DOCKER_GRPC_VERSION and
DOCKER_GRPC_LOCATION
* `generate_library.sh` will now be able to avoid downloading the gRPC
plugin if the computed plugin version is the same as DOCKER_GRPC_VERSION
(all this via `utilities.sh`).
