deploy the shuffle server.
+Some benchmark tests among different JDK is as below:
+(using spark to write shuffle data with 20 executors. Single executor will
total write 1G, and each time write 14M.
+Shuffle Server use GRPC to transfer data)
+
+| Java version | ShuffleServer GC | Max pause time | ThroughOutput |
+| ------------- | ------------- | ------------- | ------------- |
+| 8 | G1 | 30s | 0.3 |
+| 11 | G1 | 2.5s | 0.8 |
+| 18 | G1 | 2.5s | 0.8 |
+| 18 | ZGC | 0.2ms | 0.99997 |
+
+Deploy Steps:
1. unzip package to RSS_HOME
2. update RSS_HOME/bin/rss-env.sh, e.g.,
