Enable grpc interceptors in serve Context like userHandlers are enabled

[nicolaslopezbravo]

What would you like to be added?

embed's serve creates a new v3rpc grpc server but doesn't make use of the interceptor option. Could serve context have userInterceptors similar to userHandlers so the user can add & pass in interceptors to the grpc server?

Why is this needed?

Extends existing capability, allows for user to add all sorts of useful middleware, monitoring, auth, etc.

CC @ahrtr just want to check if this is reasonable, I can implement it if necessary. Is there any permissions required to create a pr?

Nevermind, this is the feature I was looking for #14066. Sorry I'm a bit new to etcd, are releases scheduled at any particular intervals? Looking to see when v3.6 will be released https://github.com/etcd-io/etcd/blob/main/CHANGELOG/CHANGELOG-3.6.md

Hey @nicolaslopezbravo thanks for your question - for etcd 3.6 we need to address the remaining items in this roadmap: https://github.com/etcd-io/etcd/blob/main/Documentation/contributor-guide/roadmap.md#v360

I'll close this now given the feature is ready and will be published in 3.6.
