    ZEPPELIN-1454: Wrong property value on interpreter page

    ### What is this PR for?
    If for some reason (for example permission issue in file system) while 
saving interpreter setting, UI shows wrong value till the next restart.
    IMO interpreter.json should be the source of truth, that should always be 
reflected on UI
    
    ### What type of PR is it?
    [Bug Fix]
    
    ### Todos
    * [x] - read from file-system after saving
    
    ### What is the Jira issue?
    * [ZEPPELIN-1454](https://issues.apache.org/jira/browse/ZEPPELIN-1454)
    
    ### How should this be tested?
    Change file system permission of "interpreter.json", and make it readonly, 
then on interpreter setting page try and change any property and refresh the 
page, refer screenshot
