### What is this PR for?
The root cause is due to ast api is changed after python 3.8, see https://github.com/ipython/ipython/pull/11593.
* The PR fixed this issue in `zeppelin_python.py`.
* This PR add tests for Python 3.8 for both python interpreter & spark interpreter (spark 2.4 doesn't support python 3.8, so there's no python 3.8 test for spark 2.4). `jupyter_client` 5 is used because jupyter_client 7 doesn't work (tracked in ZEPPELIN-5533)
* bokeh test is disabled for flink interpreter. Because pyflink's dependencies conflicts with bokeh2.

### 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
