Protobuf files available for generating clients

[tnickelsen]

Description

Protobuf files are used for gRPC contract for server and client. Right now .proto files are implemented by the server, but clients needs to implement them as well in order to call the server. Thus the .proto files needs to be distributed/availble to/fer server and clients.

One approach is using references to tags in Github repository.
Another is via nuget. See links:

• Enable referencing proto files in NuGet packages grpc/grpc-dotnet#183
• gRPC JSON transcoding - msbuild includes proto dependencies dotnet/aspnetcore#44999
• https://stackoverflow.com/questions/66844211/sharing-one-grpc-proto-file-for-all-solutions

Acceptance criteria

• Documentation updated with how to generate a client

Martin prefers a solution where client projects refer to the protobuf-files in tags in this github repo

[MartinSchmidt]

Yes, I think it would be best for consuming applications to reference the raw protobuf files, this ensures our documentation and examples are sufficient for all client languages. If we begin creating nuget packages, then dotnet clients might be easier, but other languages might be harder, since we might not be as focused on proper documentation.
