### What is this PR for?
The pr is to fix a bug that will make the **ipython** queue listener, overuse cpu. After this fix, cpu usage should be way lower.
Also there is a bit of refactor to use only one queue to ensure message will be order even with a sleep.
Also, the refactor is reducing the number of line and code duplication

### What is this PR for?
The pr is to fix a bug that will make the **ipython** `execute_interactive` hang forever if a auto `complete` call is make at the same time. (see unit test for example that is failing on master).
For now the fix is to synchronize those method : `execute` / `complete`. It will not bring regression because anyway, the kernel does not support concurrent execute and auto complete (see https://github.com/jupyter/notebook/issues/3763)

### What is this PR for?
There're several places in zeppelin to launch processes, such as interpreter process launch, python process launch. Sometimes it is very hard to diagnose if the process is failed to launch or some error happens during its lifecycle. This PR introduce ProcessLauncher to encapsulate process launch. ProcessLauncher will do most of the process launching stuff but also allow for customization. E.g. how to check the process is started properly. And when error happens, ProcessLauncher will capture the necessary error output for further diagnose.

This PR is pretty big, most of the code changes is due to regeneration of thrift code.
Another improvement is introduce the builder pattern of InterpreterContext as the arguments of InterpreterContext constructor is too many.

This PR is trying to remove the code duplication between PySparkInterpreter and PythonInterpreter. So here's the main things this PR did:
* PySparkInterpreter extends PythonInterpreter
* PySparkInterpreterTest extends PythonInterpreterTest so that we can verify PySparkInterpreter can do whatever PythonInterpreter can do
* Move interpreter/lib/python/backend_zinline.py and interpreter/lib/python/mpl_config.py into python module, so that python module can ship these resources together.
