### What is this PR for?
This PR will change the CI-System from [Travis](https://travis-ci.com/) to [GitHub Actions](https://github.com/features/actions)
**Advantages:**
- [high usage limits](https://docs.github.com/en/free-pro-teamlatest/actions/reference/usage-limits-billing-and-administration#usage-limits)
- No CI setup is required from the contributors
- good integration with GitHub Pull request
**Disadvantage:**
- At the moment we have some flappy tests and external dependencies. Both can cause a failed test, but we cannot restart a single job, only the entire workflow.
**Miscellaneous:**
- CI is triggered with every push event
- CI is triggered when PR event is open and synchronized
- Selenium test is updated to python3
- The Livy-Python2 test is dropped because Python2 has reached [the end of its lifetime](https://www.python.org/doc/sunset-python-2/)

### What is this PR for?
This PR is to fix the issue of FLINK-16936 by a workaround, already creating tableenv before execution scala or python code. Building tablenv is pretty light which won't cost much time. So it is acceptable for this workaround. Another this PR try to fix is the ClassLoader issue for PyFlinkInterpreter. This PR will always set classloader before executing python code so that pyflink api can call udf defined in scala.

### What is this PR for?
In ZEPPELIN-4480, we introduce zeppelin-jupyter-adapter which build a bridge between zeppelin and jupyter, zeppelin can extends this class to leverage any kernel of jupyter.
After a second thought, I think it is not enough. We can allow user to use jupyter kernel directly instead of implement one by one. So the purpose is to allow user use jupyter kernel like this
```
%jupyter(kernel=ipython)
python_code
...
```
Of course user can enhance the jupyter kernel in Zeppelin, e.g. IPythonInterpreter of Zeppelin can enhance the ipython kernel by adding support of ZeppelinContext

This is allow user to specify resourceName when they want to save the paragraph result into ResourcePool. Before this PR, user don't have control on what name of the saving resource name. It is associated with noteId and paragraphId, but this is not a good solution. Because when you clone the note, noteId will be changed, and you have to change the noteId in code as well. This PR is trying to allow user to set resource Name for the saving paragraph result.

### 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.
