Why downgrade the version of JDK?

Why downgrade the version of JDK?

In the past practice process, I found that whether it is a developer or a community user, the JDK version is still mostly 1.8.0. In our Docker compiled image, the default JDK-11 version is adopted. Not paying attention to the JDK version problem often leads to taking time to compile, but getting a binary file with an incorrect JDK version, so I want to change the default JDK version of Doris's Docker compiled image to JDK-1.8.0.

At the same time, I also sent a discussion email to the dev mailing group, welcome to reply to the discussion, thk~

As we disscussed in email and wechat, doris will support jdk 8 as default jdk so I will merge it.
