    [ZEPPELIN-3249] Add support for streaming table

    ### What is this PR for?
    Since Zeppelin support streaming from various backends, I think it will be 
useful if even tables (and later graphs) can also be streamed.
    
    ### What type of PR is it?
    [Improvement | Feature]
    
    ### What is the Jira issue?
    * [ZEPPELIN-3249](https://issues.apache.org/jira/browse/ZEPPELIN-3249)
    
    ### How should this be tested?
    I have done it using shell interpreter, but this should work for all other 
backends as well
    ```
    %sh
    echo "%table"
    echo "Col1  Col2"
    echo "1     2"
    sleep 1
    echo "3     4"
    echo "5     6"
    sleep 2
    echo "7     8"
    sleep 3
    echo "9     10"
    echo "11    12"
    sleep 4
    echo "12    13"
    ```
    
    ### Screenshots (if appropriate)

    ### Questions:
    * Does the licenses files need update? N/A
    * Is there breaking changes for older versions? N/A
    * Does this needs documentation? N/A
