Lee moon soo 850fd81a51 [ZEPPELIN-212] Multiple paragraph results
### What is this PR for?
Currently a paragraph can display only a single type of result.
For example
```
print("""
%text textout
%html htmlout
""")
```

will display only last display system detected, "htmlout".

This pr implements multiple results supports, so not only the last, but also all the display systems in a paragraph outputs can be displayed.

To do that, Note.json format need to be changed. from

```
   paragraph : [
      {
          result : {
              code: "",
              type: "",
              msg: ""
          },
          config : {
             graph : {},
             ...
          },
          ...
      },
      ...
   ],
   ...
```

to

```
   paragraph : [
      {
          results : {
             {
                code: "",
                msg: [
                   {
                        type: "",
                        data: ""
                    },
                    {
                        type: "",
                        data: ""
                     },
                     ...
                ]
          },
          config : {
             results : [
                {
                    graph : {},
                },
                {
                    graph : {},
                },
                ...
             ]
          },
          ...
      },
      ...
   ],

println(s"""%table key\tvalue
sun\t100
moon\t200

""")

// display text again
println("""%text""")
