Usability improvement

Being used to the 2.x UI (ie: ibm.biz/restapi), to me it wasn't obvious that the "Try it out" button now enters into a development mode. I was expecting the "Try it out" button to actually execute a request, like it did in 2.x.

With 3.x, if I want to try out multiple endpoints I must click "Try it out" for each one, and then execute.

This issue is to suggest that we have a global toggle at the top of the UI that enters the "development mode", so that you can keep the default "documentation mode", but have an easier way to enter the development mode for all the endpoints. This would reduce the amount of buttons in your UI by 1 for every endpoint.

If we think about it, the "Authorize" button at the top means nothing if we're in documentation mode, since we won't be invoking any APIs.

So I suggest we replace the Authorize button with something like "Configure UI" (or similar) where the popup window/wizard would have a checkbox that said "Enable development mode", and when that checkbox was enabled then the authorization configuration inputs would show up and every endpoint would have the Try it out button, ie: execution.

This also creates a place where other configuration can go in the future from extenders of the UI - for example, if someone wants to hook up generators from the UI, filter tags, etc.

Start by tracing the UI entry points for the "Try it out" and "Authorize" controls and how they switch between documentation and development mode. Define the global configuration flow and confirm that enabling development mode applies to every endpoint while preserving a documentation-only default; done means the proposed configuration and authorization behavior is consistent across the UI.
