Add Delete Visualization Button to Visualization Editing View

[anottrott]

If a user has 100s of visualizations in a single space, it becomes impossible to remember which visualization is which by reading the visualization title. If a user chooses to delete a visualization it would be helpful to do this from within the Edit Visualization page so that the user can see what the visualization looks like before deleting it

two ways to possibly solve this:

• from visualization library list: see a preview/thumbnail of the visualization
• add delete to lens editor and resolve where to go after you delete (back to dashboard in some cases, back to visualization library in others, ...?)

Since the visualize library is no longer part of the new menu navigation and we will move towards dashboards and discover inline editing more and more in the future. I propose we close this issue, are you ok @markov00 ?
