Add server information to robustness response information

[serathius]

What would you like to be added?

Add MemberId to from response header to the model.EtcdResponse. Ensure it's added to json response and visualized in the porcupine linearization.

Edit: Would be great to have this information showing in tooltip, for that we need anishathalye/porcupine#39

/cc @sneaky-potato @henrybear327 @nwnt

Why is this needed?

Makes it easier to debug linearization failure

Hey, I see its still open, can i work on this?

[jihogh]

I'd also be interested in working on this if possible!

[serathius]

@nwnt are you still working on it?

[jihogh]

Once we figure out if nwnt is currently working on it do you mind if I take this one @slyt3 ? I’m new to etcd’s codebase and I’m not deeply familiar with gRPC or the client layer yet, but this issue seems like a great simple entry point to learn the request/response flow and the metadata propagation, if not I completely understand! Thank you so much!

[slyt3]

@jihogh Sure, go for it! 💪

[jihogh]

Sounds great, I really appreciate it! Waiting on further guidance @serathius Thank you again!

[nwnt]

Yep, still working on this. had some progress but I was out of office for a while. will get something out by this week.

[jihogh]

@nwnt do you mind if I take a stab at this? Unless you already have significant work done and you wanna finish it! (is this poor form? I’m not 100% familiar with open source contributions, please let me know!) Just asking because it looks like a great first issue :)
