Migration ZEPPELIN from JUnit4 to JUnit5

This is the umbrella ticket to migrate ZEPPELIN from JUnit4 to JUnit5 with following steps:

1  To support running both jUnit 4 and jUnit 5

2  Module based migration of old tests from JUnit 4 to JUnit 5.

3  Remove dependency of `junit-vintage-engine` so that only JUnit 5 test can be runned.

The first step was finished. Now we are working on step 2. I think we can refer to `JUnit 5 Migration Guide` of other project to do the migration.

Here is JUnit 5 Migration Guide` of  Apache Flink

All JUnit 5 migration related tasks are welcome to be created under this umbrella. And welcome to the discuss this ticket.
