JoshRosen opened a new pull request, #36645: URL: https://github.com/apache/spark/pull/36645
### What changes were proposed in this pull request? This PR cleans up the `spark.rpc.numRetries` and `spark.rpc.retry.wait` configs, both of which are ununused. ### Why are the changes needed? Since SPARK-19450 / #16790 in Spark 2.2.0, both of these configurations are unused and setting them has no effect. Marking the configs as deprecated and cleaning them up from the docs helps to avoid user confusion. In addition, this cleanup slightly improves the performance of constructing `RpcEndpointRef`s because it removes two unused fields that were initialized by reading the deprecated configs. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? n/a -- This is an automated message from the Apache Git Service.
