Zeppelin 688
### What is this PR for?
When a user use Spark interpreter, the result comes out with result number
message like :
```
res0: Int = 250
```
Someone might want to print this REPL output with their result, but others
may want to see the result only since sometimes this output is too verbose. So,
I just want to give an option to hide this REPL output to those users.
The default value of `zeppelin.spark.printREPLOutput` is `true`. This
status is as-is. Users can hide REPL output only when they changes this
property `true` to `false`. In this case, they can check the result by
specifying such as `print(some_variable)`.
### What type of PR is it?
Improvement
### Todos
* [x] - Add a property `zeppelin.spark.printREPLOutput`
* [x] - Add Spark interpreter property table to `docs/spark.md`
### What is the Jira issue?
[ZEPPELIN-688](https://issues.apache.org/jira/browse/ZEPPELIN-688#)
### How should this be tested?
After applying this PR,
1. Create spark interpreter for this test and change
`zeppelin.spark.printREPLOutput` property value `true` -> `false`
2. Create a notebook and bind interpreter what you made.
3. Write `val a = 250` down and run this paragraph. Then you can check
the any output is not shown although paragraph status is **FINISHED** (This is
the result of this PR).
4. Run `print(a)` in the next paragraph. Then finally you can get a
result `250`.
### Screenshots (if appropriate)
### Questions:
* Does the licenses files need update? No
* Is there breaking changes for older versions? No
* Does this needs documentation? I added Spark interpreter property table
to `docs/spark.md`.
