### What changes were proposed in this pull request? Part of importing the Spark Connect Gateway reference implementation into `apache/spark-connect-gateway` as a series of small, bottom-up PRs (tracked in the do-not-merge reference PR #1). This adds the `scg-pool-k8s` crate — a Kubernetes service-watch backend `Pool`. It watches a `Service`'s `Endpoints` object in a given namespace and exposes the ready endpoints as the routing backend set, so the gateway's backend membership tracks the Spark Connect pods dynamically. This is the dynamic counterpart to the fixed-membership `scg-pool-static`. `scg-pool-k8s` depends on the `scg-routing` crate whose `Pool` trait it implements, and pulls in the kube / k8s-openapi client stack. It is imported as its own PR (rather than grouped) because of that larger dependency surface. It compiles and tests on its own (unit tests plus a router integration test) and is appended to the workspace `members` list. It is consumed later by the `gateway` binary. ### Why are the changes needed? Implements the reference gateway from the approved SPIP (SPARK-58455), imported one reviewable piece at a time. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? `cargo fmt --all --check`, `cargo clippy --workspace --all-targets -- -D warnings`, `cargo build --workspace`, and `cargo test --workspace` all pass locally. ### Was this patch authored or co-authored using generative AI tooling? Yes, co-authored with Claude Code. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
