Java client dependencies

The OpenTelemetry metrics serialization is used as metrics payload the payload of the telemetry metrics sent to the broker. This will require us to include the Java Bindings for the OpenTelemetry Protocol (OTLP) as a dependency for the Java client.

implementation("io.opentelemetry.proto:opentelemetry-proto:0.11.0-alpha")

The OTLP Java bindings library is a minimal dependency and itself requires only the Google Protobuf serialization library:

implementation("com.google.protobuf:protobuf-java:3.18.0")

This will allow us to build up Java objects in memory that reflect that specification and easily serialize them to the required transport wire format.

The Gradle build process will be updated to shadow the OTLP Java bindings library and its dependencies to avoid in-JVM versioning conflicts.
