### What is this PR for? [Powermock](https://github.com/powermock/powermock/issues/929) is not supported in JUnit5. We should not be dependent on Powermock. This PR removes the Powermock dependency from the Docker plugin. It also makes some refactoring. Instead of using environment variables directly, this possibility of configuration is moved to ZeppelinConfiguration. In order not to break the naming scheme in ZeppelinConfiguration, the environment variables that were previously accessed must be changed. `CONTAINER_SPARK_HOME` -> `ZEPPELIN_DOCKER_CONTAINER_SPARK_HOME` `UPLOAD_LOCAL_LIB_TO_CONTAINTER` -> `ZEPPELIN_DOCKER_UPLOAD_LOCAL_LIB_TO_CONTAINTER` `DOCKER_HOST` -> `ZEPPELIN_DOCKER_HOST` `DOCKER_TIME_ZONE` -> `ZEPPELIN_DOCKER_TIME_ZONE` Except for DOCKER_TIME_ZONE, I have not found any references in the documentation or other files. ### What type of PR is it?
