    METRON-1146: Add ability to parse JSON string into JSONObject for stellar

    ## Contributor Comments
    This pull request allows the ability to parse a given JSON string and return a JSON object. Here is an example:
    `MAP_GET( 'bar', PARSE_JSON_STRING(  '{ "foo" : 1, "bar" : 2}' )`  would yield `2`.
    
    Another slightly complex example would be:
    `MAP_GET( 'foo1', GET_FIRST( PARSE_JSON_STRING('[{ "foo1":"a", "bar1":"b"}, { "foo2":"c", "bar2":"d"}]'))` ==> would output `a`
