Publish a prebuilt jar with BEP protos to maven

[agluszak]

Description of the feature request:

In bazel-bsp we have to pull the entire Bazel source code just to get the BEP protos. It would be much more convenient for us if you published the BEP java proto library to maven.

We use the following targets from Bazel:

        "@googleapis//:google_devtools_build_v1_build_events_java_proto",
        "@googleapis//:google_devtools_build_v1_publish_build_event_java_grpc",
        "@googleapis//:google_devtools_build_v1_publish_build_event_java_proto",
        "@io_bazel//src/main/protobuf:deps_java_proto",
        "@io_bazel//src/main/protobuf:failure_details_java_proto",
        "@io_bazel//src/main/protobuf:invocation_policy_java_proto",
        "@io_bazel//src/main/java/com/google/devtools/build/lib/buildeventstream/proto:build_event_stream_java_proto",
        "@io_bazel//third_party/grpc:grpc-jar_checked_in",
