Include missing gRPC classes when creating a fat JAR

[bevzzz]

creating a uber jar with our client is not easy as it doesn't include many GRPC dependencies

Useful links:

• gRPC has a dynamic resolution to load their name resolution provider
• At load time, it would inspect & load all classes that are implementing an interface
• Related GitHub issue: Address types of NameResolver 'unix' for 'localhost:8443' not supported by transport grpc/grpc-java#10826

Their parent POM include a dependency with gRPC - and it changed the gRPC from Weaviate in the classpath 💥
