[FeatureRequest] add a "rename" option when saving existing visualization with different name

[truebit]

Describe the feature:

• Scenario:
  1. Created a visualization in Kibana with name "foo"
  2. edit the visualization "foo", Press "Save" button.
  3. And I also want to rename the visualization to "bar".

Now the logic is to create a new visualization named "bar" and the old visualization "foo" unchanged.
If I do not want to keep the old "foo", I need to got to Settings to delete the old visualization. It's very inconvenient; and I have to be careful not deleting the useful ones in bunches of visualizations

• UI Suggestion:
  • add a checkbox beside "Save" button with a label "rename". if checkbox being checked, it would rename the visualization. (Very likely the "Store time with dashboard" checkbox in saving dashboards)

@truebit This feature already shipped in 5.2: #9087

The default behavior of the save dialog will rename the object, and you can choose to opt-in to creating a new object entirely.
