ZEPPELIN-1328 - z.show in python interpreter does not display PNG images in
python 3
### What is this PR for?
Support for plotting PNG images via matplotlib inline for the python
interpreter was recently added (#1329). However, these changes did not work for
python3 since it handles strings differently. This PR aims to make the inline
plotting compatible with both python 2 and 3.
### What type of PR is it?
Bug Fix
### What is the Jira issue?
* [ZEPPELIN-1328](https://issues.apache.org/jira/browse/ZEPPELIN-1328)
### How should this be tested?
In a python interpreteter cell, make sure the following produce an image:
```python
%python
import matplotlib.pyplot as plt
import numpy as np
x = np.arange(5)
plt.plot(x)
z.show(plt, fmt='png') # Repeat for fmt='svg'
```
This should be tested for both python2 and 3 interpreters (via the
interpreter settings page).
### Questions:
* Does the licenses files need update? No
* Is there breaking changes for older versions? No
* Does this needs documentation? No
