[#674] feat(docker): use JDK11 as the default java version in Dockerfile

[zuston]

What changes were proposed in this pull request?

Use JDK11 as the default java version in Dockerfile when deploying shuffle servers on K8s.

Why are the changes needed?

As the GC problems mentioned in #674, I upgraded the JVM version from JDK8 to JDK11 for shuffle server. And after benchmark, I found the effect of the upgrade is remarkable. And it also works well with Hadoop3.1.1

Based on above practice, it's better to use JDK11 as the default java version to improve stability

Does this PR introduce any user-facing change?

Yes

How was this patch tested?

Have tested in production env.

Does it help when the java version in pom.xml is still 1.8?

GC is part of java runtime, it shouldn't matter whether the code is compiled with Java 1.8 or Java 11.

Could you help review again? JDK11 has been applied in our production env, it works well with hadoop3.1.1 @advancedxy

If it could work well with hadoop client. I think this is a good start.

Would you mind create an umbrella issue to tracking all the issues needed to promote using JDK 11 here?
If we are going to promote JDK 11, some of the following work(not exclusive) should be done:

1. CI workflows to add JDK11 to run all the tests, not just the compile and build only.
2. related build system/files, this docker file is one for example
3. Documentation changes.
4. benchmark result etc.

The code itself LGTM.
However would you mind to modify the RP title to reflect the actual change, since it only changes the dockerfile

Also, would you mind to provide a bit more information about how it is tested.

Done.

Yes, more detailed info will be exposed in #674
