SUBMARINE-942. Make experiment ID consistent with TFJob and PyTorch Job

[kevin85421]

What is this PR for?

1. Please refer to the following two JIRA issues.

   • https://issues.apache.org/jira/projects/SUBMARINE/issues/SUBMARINE-886?filter=reportedbyme
   • https://issues.apache.org/jira/projects/SUBMARINE/issues/SUBMARINE-880?filter=reportedbyme

   In this JIRA issue, we need to make the experiment ID consistent with the name of TFJob and PyTorch Job. The difference is caused by this link. Update ExperimentId.java.

2. Update IntegrationTestK8s.md

   • "submarine-server-core" is a dependency package specified in pom.xml of test-k8s.
   • In the document BuildFromCode.md, the command to build Submarine is mvn clean package -DskipTests. However, the package will be installed into the local repository at install phase, a later phase than both package and verify phases.
   • Hence, we need to execute mvn install -DskipTests to ensure that the test-k8s module uses the latest "submarine-server-core" module.

3. Remove the field name in Experiment.java because the value of name is the same as experimentId.

@pingsutw and I are trying to figure out the root cause of a weird problem about test-k8s. Hence, this PR is not ready to be reviewed. Thanks!

Update: the root cause of the weird problem is written in the "What is this PR for?".

@jiwq Can you help me review this PR? Thanks!
@pingsutw Can you help me review the update about IntegrationTestK8s.md in this PR? Thanks!

@pingsutw I have removed the field name in Experiment.java. Thanks!

Reopen it since some tests failed.

[kevin85421]

@pingsutw In my opinion, the root cause of the CI error is caused by SUBMARINE-946 rather than SUBMARINE-942. The error message indicates that the package does not be loaded into the maven repo. If needed, I can try to fix the error.

[pingsutw]

But tests passed after I revert SUBMARINE-942.

@pingsutw This is because other pull requests do not change the submarine-server-core module. I will rebase the merged commits to reproduce the CI failures.
