Add Plotly output support to notebooks

With this change, Plotly types will be successfully rendered in a Notebook.
Currently they have a default width of 700px with a scrollbar if the window size is smaller (this matches other notebook viewers).
The Plotly library is dynamically required to avoid startup time perf hits. This is something we could look at for other components too.
