Support google.golang.org/grpc v1.69.0

[MrAlias]

The function google.golang.org/grpc/internal/transport.(*http2Server).WriteStatus was renamed to function google.golang.org/grpc/internal/transport.(*http2Server).writeStatus: https://github.com/grpc/grpc-go/blob/317271b232677b7869576a49855b01b9f4775d67/internal/transport/http2_server.go#L1045

Looking at updating our definition of probe.Uprobe to handle this behavior split.

@MrAlias what are you thinking for the split? We have the MinVersion struct right now but I could see that getting messy, especially for situations where it's just a rename. Do you have an idea?

[MrAlias]

I'm still prototyping, but the current idea is to update the Uprobe with a version matching criteria and evaluate this during loadProbe.

It looks like handleStream's signature also changed: https://github.com/grpc/grpc-go/blob/317271b232677b7869576a49855b01b9f4775d67/server.go#L1735

Still working on it.

Update: The parent span context is no longer being found for the server spans. Digging into why.

http2Server.operateHeaders also changed: grpc/grpc-go@2a18bfc#diff-4058722211b8d52e2d5b0c0b7542059ed447a04017b69520d767e94a9493409eL362-R362

This is where the parent span context is supposed to come from. Updating.

This looks to have been my mistake in reading the embedded Stream correctly from ServerStream.
