SPARK-9767 remove `ConnectionManager` and related classes, the configuration item `spark.core.connection.ack.wait.timeout` previously used by `ConnectionManager` is no longer used by other Spark code, but it still exists in the `configuration.md`, so this pr cleans up the configuration item from `configuration.md`. ### Why are the changes needed? Clean up useless configuration from `configuration.md`. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested?
