Recreate the "Keyword" section of dashboard with Watson tools.

[MichaelClifford]

As a data scientist I want to evaluate the capabilities of IBM NLU/Discovery/Studio so that I can determine when and where to leverage it in future projects. To do this we will recreate one existing graph from our Fedora mailing dashboard. The graph that we will recreate will be the "Keywords" plots following the Watson demo provided.

Acceptance Criteria:

• New notebook that recreates the notebooks/02_analyses/keyword_analysis.ipynb but using the Watson toolkit.
• Side-by-side comparison of results from original analysis and watson analysis
• Write up on findings as part of notebook conclusion
• Determine if native visualization is possible with Watson, if so visualize it.
