Let's implement a creation flow like the Visualize wizard:

1. Select a type of index pattern you want to create. This is an opportunity to surface explanatory text per type, to help the user understand what the options are and make an informed decision.
2. Let the user configure the index pattern by filling out a form.
3. Show the user the new index pattern with a "success" notification.

Note: In the creation process can be simplified to the point where there are no "types" of index patterns, then we can remove the first step from this wizard.
