### What is this PR for?
`ZeppelinContext.show` doesn't work for spark 1.6. The root cause is that `Dataset` is also available in spark 1.6, so the following line will be false when cls is `Dataset` while o is `Dataframe` in spark 1.6
```
if (cls.isInstance(o)) {
```
This PR create a list of supported class and make it a member of `ZeppelinContext `so that we don't need to create it every time.
