[ZEPPELIN-5999] Reduce instance objects from Zeppelin (#4726)

* Remove ZeppelinConfiguration Singelton and add MiniZeppelinServer

* Add ZeppelinConfiguration to Interpreter

* Remove static pluginmanager and configstorage

* Inject servicelocator into SessionConfiguratior

* use custom serviceLocator in integration tests

* Reorder code

* code cleanup

* Add ZeppelinConfiguration as class variable to InterpreterOption

* Avoid leaking third-party libs
